About Foldris, from BoardGameGeek:
A pen and paper game inspired by Tetris.
Players draw shapes on their paper, folding it when a line is fully filled in. Use this to your advantage to fill out previously inaccessible lines!
At the start of the game, a block card is revealed. This indicates the shape, and the column that the block "falls" down. Players can rotate the shape before filling it in using their pencil. The active player draws the shape in the indicated column, and each player to the left moves the column to the right once.
With the starting block drawn, the game proceeds with players drawing a block card on each turn, rotating and filling it in on their sheet.
When a row is fully filled in, the page is folded twice - so that only the filled in row disappears. This allows players to access rows that were previously blocked off.
You get bonus points for folding a row - additionally, if no other player filled the row during the same round, they place an obstruction block on their sheet.
You can spend points acquired from filled rows to rotate the shapes, or to remove one square from the shape.
The game ends when there's only one player remaining. If multiple players survive, the player who folded the most rows is the winner!
