Mental Blocks is a game of puzzling perspectives, with players attempting to complete a puzzle using oversized foam blocks, despite seeing only one perspective of the design.
You have to co-operate to finish the puzzle as a team, but you have a time limit, so don't just sit around staring at the pieces. Along with the time pressure, players have other challenges, such as not being able to talk or to touch certain color blocks.
Mental Blocks has 60 puzzles: 30 "family mode" puzzles and 30 "challenge mode" puzzles that ramp in difficulty. For an even wilder game, you can add a traitor to the table to block your block-building.
