The game Infinimoes tests your brain as you try to figure out how to order blocks in a way that leaves empty spaces.
You have to use to fill in the blanks. Some puzzles have places that keep repeating, which makes them even harder and more complicated.
The Z and X keys are on the bottom left of a QWERTY keyboard, which is what these keys do. The bottom left keys should work with other layouts if they are in the same place.
Use the arrow keys to: press P or Enter to open the pause menu.
X: pick up or drop tile
Hold down Z to see the list of tiles you have. Press Z + Right/Left to move between tiles in the list.
Pressing Z and Up will remove a tile.
Have fun and good luck!
