Invalid is a game about solving and fixing math equations. You have cards in your hands that are used to solve the equation, just move them to the correct position and try to fix the equation!

Move the cards by holding the left mouse button and dragging them to the equation to try to fix them.

Each time you solve a equation you get a new random card, operators are the rarest cards to get!

If you are stuck, then you lost. (yeah there is no game over screen lol)

This game was made in about 4 hours in the Trijam game jam.
