TURM

From BoardGameGeek:

TURM is a tactical card game for two players from Reinbek, in which the packaging becomes the playing field. Players work together to build towers from 0 to 12 and collect gold nuggets. The player with the most gold nuggets wins. Build towers together and earn gold. The rules are simple, but be careful: if you're not paying attention, you'll hear the dreaded ‘TOWER!' and it will be your opponent's turn. Use your gold tactically to block your opponent or gain an advantage. In this card game, the winner is the player who has collected the most gold nuggets. TURM is a tactical two-player card game about incremental tower building - simple rules, growing complexity and constant pressure from the opponent
