THE CLASSIC NUMBERS GAME

Plus &
Minus✶

A little arithmetic. A lot of strategy.
Bring your four pieces home to 25.

2 to 4 playersFriends + computersFive-game match

Each player has four pieces and eleven cards. A match has five games. Play clockwise, beginning with the player after the dealer.

  1. Choose a card. Add its signed value to the previous player's top card only. The first card must be positive.
  2. Choose one of your pieces. Move it by the resulting amount. A new piece starts from zero. A negative result moves backward; reaching or passing zero returns it to start.
  3. Land exactly on 25. A piece on 25 is home and cannot move again. Overshooting 25 sends the piece back to start.
  4. No sharing a number. Two of your pieces cannot occupy the same number, except start and 25. You cannot choose a piece at start for a negative result, or bust it from start, while another piece is on numbers 1 to 24. Any possible move must be made, even a bust. If none is possible, the card is played without moving.

A game ends immediately when someone brings all four pieces to 25, or after everyone's eleven cards have been played.

Scoring

Each piece on 25 scores 50. Each piece at start scores minus 20. Other pieces score their numbered position. The highest total after five games wins; equal totals share the win.

The 44-card pack

Seven each of +2, +3, +4 and +5; two each of +7, +9, +11, +13 and +15; one +20; and one each of −1, −3, −5, −7 and −9. Undealt cards stay concealed.

Based on the supplied original rulebook. Computer players use their own hand and public board positions.
