You get a grid of sixteen cards from The Binding of Isaac. They hide four groups of four.

Select four cards you think share something, then submit. A correct guess locks the group in and reveals what tied it together.

You have four lives. Each wrong guess costs one, and the run ends when they are gone.

Some categories are meant to be tricky, and one card can look like it fits in two places. That is the whole game.
