BITS Mitbringspiel is a smaller version of BITS with similar game play: Each player has a board on which they place single- and double-colored tiles turn by turn, based on random card draws. Players score or lose points at the end of a round based on the color combinations they create, as determined by randomly-selected scoring cards that were revealed at the start of that round. For example, in one round you want to create "T" shapes of a single color, while avoiding "I" shapes. After three rounds, the game ends and the player with the most points wins.
The rules include a solo variant in which you're challenged to score as many points as possible.
BITS Mitbringspiel differs from BITS as it includes fewer tiles, lasts only three rounds instead of four, and the tiles are cardboard instead of plastic.
