Nervos

Nervos is a real-time puzzle game that combines elements of Ubongo[/thing] with Ghost Blitz[/thing]. The game includes a stack of puzzle cards and 4 polyomino pieces. Each puzzle card shows a shape that can be made using exactly 3 of the pieces. A puzzle card is revealed and the players race, mentally, to determine which piece is not used. Once they feel confident, they grab the piece, and then have a few seconds to "show their work" by completing the shape with the other pieces. The games ends when a player successfully completes 4 cards; alternatively, players are eliminated if they incorrectly answer 3 cards.
