Although you will be racking up millions (or billions or etc) dollars of 'cash' pretty fast in Blush Blush, it's Diamonds that act as the premium currency for actually unlocking and enhancing features. And while you can always support the developers and Buy More With Real World Money, which purchases are worth making and when is not always super clear, especially if you're brand new.

This guide is oriented towards helping you learn how to obtain Diamonds, and also to help make informed decisions about what to spend them on.

You can obtain Diamonds for free in the following methods:

• Daily Missions: In the top right, there is always an ongoing 'outfit' or 'cut-in' or similar event. This is a clickable button. There will be a variety of tasks that require an amount of Time Blocks dedicated to them for a short time before they can be purchased. It seems like 6/7 days of the week, one of these missions is "Spend 5 time blocks for an hour to receive 1 Diamond". On the remaining day of the week, this will either be 8 time blocks for 3 Diamonds or a permanent +1 Time Block. You should do these every day. (The Epic Task should also be clicked twice each day, it costs 0 time and is how you best get bonus outfits/cut-ins/etc) The Daily Missions reset at roughly 5 PM Pacific/8 PM Eastern (the time may adjust with Daylight Savings, etc).
  
• Achievements: Every time you raise a Boy to a new threshold you've never reached before, you'll earn a related achievement, and some Diamonds to accompany. These thresholds are at each new named level, as well as additional thresholds at Lover +1, +5, +10, and every ten thereafter up to +100. Most boys give 1 Diamond at each level, with 3 Diamonds instead at Lover +1 and Lover +100. Due to their increased demands, all boys after Garrett give 2 Diamonds instead at the various Lover +x thresholds, and due to being basically the final bosses, Stirling and Scale give 3.

The achievement-unlocked Diamonds may make it feel early on like you are rolling in Diamonds when you first play, but those will very quickly slow down, especially if you don't spend your Diamonds smartly!

You can also purchase Diamonds with real money. If you're impatient for some early speedups it's not out of the question, but if you do want to spend money, consider the following things first: the Paid-only content

• Sven is 5$, and while it will take a bit of play before you can level him up, comes with the amazing quality of life feature of adding a button to instant-purchase all required items/finish all dates for a Boy without a ton of clicks on your part.
  
• Cole is 3$, and while his benefits will be less immediately apparent, he also unlocks a Job (Mystery Solver) which starts off poor, but has exponential scaling to its returns - it that can very quickly become the best source of money in the game.
  
• The Fully Voiced DLC is 2$ and adds a lot of charm to the game, and includes lines for all alternate costumes and CG scenes and even the NSFW version-specific content. It does nothing for your play however.

If you've obtained those and still are interested in spending money to enhance the game, Wait for a Sale to buy Diamonds. Not only do Sales tend to give roughly 25% discounts, but they also often come with bonus costume unlocks for purchasing any Diamonds during that time, which, hey, might as well, right?

At its core, Blush Blush is an idle game about Multipliers. As you build up your Boys and stall out, you soft reset in order to do it faster, right?

Well, that's why the Permanent Speed Boosts are so important. They're located in the "Boosts" category of the shop, and are multipliers to everything else in the game. Job speed, hobby increase speed, natural heart gain - it's all affected by this, the same way your Reset Boost is. But also, this is multiplicative with your Reset Boost.

If you have a Reset Boost of 50x but no Permanent Speed Boosts, you have a total game speed of 50x.

If you have a Reset Boost of 50x but have all three Permanent Speed Boost, you have a total game speed of 3200x.

If that seems like a massive jump to you - yes, yes it is, and that's why it's so important. Once you hit the mid-tier boys, and especially the last few, the game is absolutely designed expecting you to have the maximum Permanent Speed Boost.

There are three to grab:

• 2x Boost for 25 Diamonds
  
• 4x Boost for 50 Diamonds
  
• 8x Boost for 100 Diamonds

Each of these purchases can be done once only, and they are multiplicative with each other. This means it's not actually beneficial to hold out for the 8x when you start - buy the 2x and 4x first, and you'll get the same bonus 25 Diamonds earlier. Then, once you save up your next 100 diamonds, buy that 8x. It'll take a while, but you will be extremely glad you did.

I want to stress this again: Buying all three of these multiplies your total game speed by 64 times, and the game absolutely expects you to get these. Anything else you can spend Diamonds on before this point is an inefficient waste. Yes, even Poe - he's scaled like a later Boy, he expects you to have these.

By the time you'll have purchased the Permanent Speed Boosts, you'll probably have noticed the other major spending you can do with Diamonds - speeding up individual Jobs and Hobbies. This is 10 Diamonds for a permanent 8x to that Job/Hobby. This is multiplicative with Reset Boosts and Permanent Speed Boosts.

However, these are definitely less necessary than the Permanent Speed Boosts, and not just because they head to a specific singular thing.

Hobby Speed Boosts are pretty important for the long game, and you will eventually want all of them. Even with a 1000x base Reset Boost, 64x Permanent Speed Boost, and an individual hobby boosted, it still takes roughly a full day to raise a hobby by one level at around 56. And hobbies cap out at 70. By the time you play long enough for 'oh but these will cap and no longer provide a benefit' to matter, you will have gotten absurd amounts of value out these.

Prioritise Hobby boosts based on what you actually need in order to break new thresholds for your Boys and get Achievements. There's no point in boosting Caring's speed if the stat checks you're actually being required to meet are Observation and Smart.

Jobs are a bit more complicated. You do not at all need to boost every Job in the long run - in fact, many are actively not worth it. For instance, boosting the first job of Sew Pro might raise its final level from, say, 500 thousand to 4 million per second - but at the same time, boosting Farmer instead would raise it from 22 billion per second to 176 billion. One of these is a vastly larger return for your investment (it's Farmer, if that wasn't clear).

Once you're sitting comfortable with your Hobbies, I suggest augmenting the following jobs:

• Mystery Solver, if you have Cole to do so. Once you can get this job to a point where you can level it up decently quick (which boosts help with), it will start to outstrip other jobs quickly, and I'm pretty sure it is the highest earning Job in the game at its maximum level, with a Time Block To Income ratio nearly 3x higher than that of the Farmer. It's just so good and available so early.
  
• Politician, Pharmacist, Florist, Cryptominer, Fundraiser. These jobs take a notably long time to level compared to others, and will frequently be the blocks that prevent you from further increasing Lover + levels on Boys (especially Politician). They also tend to cost sharp amounts of Time Blocks on their first few levels, which you'd like to have blitzed through as soon as possible on each reset in order to reclaim those blocks for other things.
  
• Farmer is less likely to block off character progression, and once you get to a point where you can push through the first couple levels in a reasonable time, it actually levels much quicker than the previous jobs. However, if you find yourself needing more raw income, this is the next best job after Mystery Solver for raw income.

The rest are largely optional. You can unlock more to increase your income further, but each additional lower-level job you augment is going to increase your gains less and less.

Okay, so we've gotten ourselves to a spot where our progression through the game isn't being outstripped by a snail. Now what?

The next thing most people will be interested in purchasing with Diamonds is the stuff that unlocks content.

Extra Characters (Poe, Cashew, etc), are by far the most enticing. These were capable of being earned as rewards for the events on their release, but if you missed them, they're a whopping 200 Diamonds. You do unlock achievement tracks for them that get you some Diamonds in return, but it's not going to make up for what you got. However, let's be real - you're playing this game for those characters anyway, so once you've got your permanent boosts going, it's time to save for this.

However, be aware that the extra boys have very high requirements. They're comparable to Stirling, the eleventh boy - so if you aren't yet progressing well enough to worm your way into Stirling's good graces, don't expect the extra boys to go any better!

After that, we have Costumes. These are... very low priority, honestly. Yes, it's nice to play dress up, but the characters honestly only get one new line. Plus, Costumes do nothing until you can equip them, which is at Lover +1 - which for some Boys will be a while away. If you do want to pick these up, pick up the Bundles for 60 Diamonds - It gives you all twelve for half the total price.

Finally, there are the new Extra Phone Flings. At 10 Diamonds each, these are a cheap little boon that do come with their own three extra CGs. You can get a character's fling once they hit Lover +1. Given their cheap cost, feel free to get any for boys you'd like more content of.

You should only be considering these purchases once you have the Permanent Speed Boosts, the Hobby boosts, any Job boosts you want, and all the Content you want.

But maybe you have reached that point and run out of things to spend your Diamonds on? Alright, here's the considerations on a more permanent front:

• Holding for New Content is a solid idea. Keeping diamonds around for diamond-only new content (such as the new Phone Flings) is a good idea. Also, while you can get new Event content by simply booting up the game once a day and making sure to click the event button in the top right, then claiming your daily token... well, sometimes life will happen and you'll miss a day. You can make up for missed days in events and still get the reward - but you'll need to pay in diamonds to make up for missed days!
  
• Time Blocks, at least, are a permanent boost. However, just playing normally will get you more than enough, especially if you are checking the Events daily and getting the occasional free Time Block from there. Remember, you don't need to have every Hobby and Job active at the same time - and every additional smaller job you have active contributes less and less to your total. If you really feel you must, then ideally you do want to buy the 10 Blocks for 80 Diamonds instead of individuals which have a vastly worse rate... but... ehhhh. Seriously, this game is meant to be played longterm over months, it's an idle game after all - and you will eventually acquire literally more of these than you can ever use.

Then we get into the Temporary Benefits, which, again, Permanent benefits may be more expensive but they are vastly more important. But if you've already got all them and have Diamonds to burn, you need to build up that Reset Boost for Scale somehow, right? Well, that's where the Temporary Boosts come in.

• Consumable Speed Boosts are the best overall accelerator, as they are once again multiplicative with everything else. The 8x is obviously the best value - you can consider it to be getting 16 days of progress in 2. However, you can purchase multiple of these and stack the benefits, and should consider doing so - with all three active, you get 128 days of progress over 2 days. If you plan to sit down and actively farm Reset Boosts, this is the way to go, as well as the best way to get resources once you've reached max Reset Boost and just need to wait for quadrillions of dollars to raise Scale's level.
  
• Time Skips are more enticing for the immediate payoff, but are a trap. Consider the following: You can pay 75 Diamonds to get 7 days of progress, or you can pay 45 to stack the three boosts and get effectively four months of additional progress. These are specifically there to bait players who are extremely impatient, but frankly, if you are extremely impatient, why are you playing an Idle Game?
  
• Finally, Skip Resets are more of an option for those who are playing the game super casually. You pay 30 Diamonds to gain the benefits of a Soft Reset you've earned, without actually setting back your progress. If you find yourself not really wanting to actively spend much time clicking away at the boys but are already in a state where you're getting a few hundred points of Reset Boost, it is a decent way to save yourself some work. It can also be used once you've reached the cap but have had to spend reset boost to raise lover levels, to get back a small amount of multiplier - but it's a very small amount.

In short: if you're lazy, Skip Resets. If you're actively looking to farm reset boost, stack up Consumable Speed Boosts and go nuts.

1: Get Permanent Speed Boosts first, they matter for Everything and the rest of the game expects them, and you can only buy them once each anyway, so.

2 Get your Hobbies boosted, get some of the top end jobs boosted, then get the Permanent Content you want.

3: Hold some spare Diamonds for future content or events where you accidentally miss a day.

4: Then, and only then, consider temporary speed boosts. Stack Temporary Reset Boosts if you plan to farm Reset Boost manually, or take Skip Resets if you're playing super chill.

And if you feel you want to buy Diamonds to support the game, wait for a sale!
