Infinite (or at least exponentially increasing) money is possible, and hilariously, actually very easy.

All you need is:
1. Play as the 'Green Father' character
2. Have two grape vines, each on different islands
3. Put one apple or cocoa tree on the same island as one grape vine
4. A Biofuel Generator adjacent to the apple / cocoa tree
5. FUEL GRAPES (of course)
6.SOME fuel production (no more than 200 really needed, just enough to get the grape's production positive)

And that's ACTUALLY it, just start hammering the space bar like its a spider dancing a jig and insulting your mother.

This works because Green Father has a special ability that lets trees steal the production of crops on the same island, including grapes when you have 'fuel grapes'. Amazingly, the things that the tree produces can still be fed into machines, INCLUDING the Biofuel generator. Thus; the tree we placed feeds into a Biofuel gen and produces fuel equal to 10x the fuel surplus, exponentially increasing the number of grapes produced by the other grape vine.

The actual results of this are interesting. Your grape production skyrockets past integer overflow and becomes negative, but before this you make close to the maximum amount of money possible. After this you can't produce any more money with grapes.


You do eventually lose when the tax cost also hits integer max, I'm not exactly sure when this happens as I've been using macros to spam space and select choices after hitting max money. I've gotten slightly past day 1000 a couple of times. It's probably possible to get slightly further if you set up trees to make multiple different products with production values siphoned off from grape vines.

I would recommend trying this quickly if it sounds fun as it will likely be patched quickly, just like the last OP glitches were.

Terracards remains a beautifully unbalanced, absolutely broken, absolutely fantastic game. Love it, and can't wait for the game to be even better with refinement and balancing.

Have fun :D
