Pentactic is a game in the line of FITS or Ubongo, but with more player interaction, where players try to place all their pentominoes on their boards while dropping stones on the opponents’ boards to prevent them from doing the same. The board features three different, overlapping playfields, in order to increase replay value: 8×8 9×7 11×6 A pentomino is a piece composed of five congruent squares, connected along their edges. There are 12 different pentominoes. Pentominoes are well known in the board game community and lots of games use them. Néstor designed the first version of Pentactic (basic gameplay) back in 1980, while playing with a home-made set of pentominoes. 30 years later, he fine-tuned it and added the 'duel' and 'multiplayer' options. There are 4 types of gameplay: Solo play (1 player): You’ll need 1 PENTACTIC set. Basic play (2 players): You’ll need 1 PENTACTIC set. Duel (2 players): You’ll need 2 PENTACTIC sets. Multiplayer (3-6 players): You’ll need as many PENTACTIC sets as players. It is recommended to use different colored sets in ‘Duel’ and ‘Multiplayer’ modes if possible. PENTACTIC sets are available in different colors.
