Catchup is a placement game with a catchup mechanism “leading to twists and surprising lead changes.” Abstract Play supports the base game on a 5×5 hex-hex board, as well as a 6×6 variant.

Catchup is a simple abstract with a devilish timing dynamic. When the hex board is full, the largest group of stones wins — but as you get closer to that lead, your opponent is allowed more placements.
