Board game MATTEL Blokus Trigon — family strategy game, for ages 7+, polygonal piece placement

Blokus Trigon by MATTEL is a family strategy board game for ages 7 and up that uses triangular polygonal pieces and a recessed board. Players place translucent triangular Trigon pieces on the shared board so that each new piece of a given colour touches at least one other piece of the same colour only at the corners. The objective is to place as many pieces as possible while blocking opponents; play continues until no more legal placements remain and the player with the lowest total of unused piece units wins. The set includes a recessed game board, 88 Trigon pieces in four bright translucent colours and a guide, and supports 2–4 players for quick, turn-based sessions.

Advantages

Blokus Trigon promotes spatial reasoning and tactical planning through polygonal piece placement and corner-touch rules. The triangular design introduces varied angles and placement possibilities compared with square-piece games, creating new blocking and expansion strategies. The translucent pieces and recessed board make placements clear and stable during play, while the rules are straightforward enough for family play yet deep enough for repeated strategic refinement.

Suitable for

• Family game nights with children aged 7 and older
• 2–4 player casual competitive sessions
• Classroom activities focused on spatial reasoning and problem solving
• Compact tabletop play in homes and recreational spaces

How to use

Set the recessed board on a flat surface and distribute the Trigon pieces so each player has their full set of same-coloured pieces. Players take turns placing one piece at a time. Each placement must touch at least one piece of the same colour at a corner only; edge-to-edge contact with same-colour pieces is not permitted. Pieces of different colours may touch along edges. Continue play until no player can make a legal placement. At the end, count the remaining unused piece units to determine the lowest total and the winner. Refer to the included guide for examples of legal and illegal placements.

Usage recommendations

Play on a steady table or surface to keep the recessed board level; allow clear sightlines for all players so placements and blocking strategies are visible. For faster games with younger players, agree in advance to limit piece sizes or use a time limit per turn to maintain pace. Store pieces in a dedicated box or bag to keep the translucent trigons together and protect the recessed board between sessions.
