There are 15 genres total. Each genre is a mini game. There are 5 games in each genre. Each game of the same genre is the same mini game that adds different levels, better rewards etc.
Below is each genre and a description of each mini game.


FPS:
Click enemies as they appear in the window.



MOBA:
Type the letters that match on the screen. This is timed.




SURVIVAL:
Move a little man across the screen and catch items that fall from the sky. Avoid some items that damage points.




SPORT:
An updated pong game. Move the cursor up and down and try to destroy blocks on the screen without losing the ball.

SOULSLIKE:
There are 9 squares to move around. Avoid damage that comes from all angles.




FIGHTING:

CAR RACE:
Your car passes other cars. Avoid hitting them. This is my least favorite game as it gives me motion sickness and I don't ever get motion sickness lol.




RPG:
There is a character on the left side of the screen and a set of 25 squares on the right. Click them for gold and avoid damage from certain squares. Use the gold to level up your character. Sword for damage, shield for protection, armor for hit points etc. When each section is full you get a boss fight. Another of my faves.
