Hiroba

About this board game

Hiroba is a strategic number-placement game for 2–4 players, with each game taking about 25 minutes. Players compete to control the most gardens by placing their numbered pebbles with care.

Like Sudoku, Hiroba challenges you to avoid placing two pebbles of identical value in the same garden, row, or column. Every placement must respect these restrictions, making each decision important as you work toward controlling more of the playing area.

The central challenge is balancing immediate opportunities with your broader strategy. You will need to think carefully about where your pebbles can go, how your choices affect garden control, and how your opponents’ placements may alter your plans.

• Place numbered pebbles strategically.
• Keep identical values out of the same garden, row, or column.
• Compete for control of the most gardens.
• Pay attention to the highly coveted Koi, which can earn precious points.

Koi add another important consideration to the contest. Controlling gardens matters, but neglecting these sought-after scoring opportunities could cost you valuable points at the end of the game.

With its blend of Sudoku-style constraints, strategic placement, garden control, and Koi scoring, Hiroba invites players to stay focused and adapt to the developing position. Can you outthink your opponents, retain control, and stay Zen?
