Acuity is a tile-matching game where players race to see who can spot the match first. There are 4 different icons, and each tile has 4 icons on it.
The game contains one of each possible tile. To start, 36 of the tiles a laid out in a 6x6 grid. Then, one of the remaining tiles is revealed. Players must match the revealed tile to an intersection of tiles on the grid. In doing so, you may rotate one grid tile 90 degrees to form the match.
The first player to see the match calls it out and scores the tile. Play continues until all tiles have been exhausted
