About this game

Rulebound is a brain arcade with twenty-six quick games across words, numbers, shapes, recall and reflexes, all in a bold riso style.

Pick a category, spend a credit and play. Credits refill automatically. Read the rule, act fast and chase a higher stamp.

WHAT'S INSIDE
• 26 games across five categories
• Weekly global standings and friends boards
• Streaks, milestones and collectable avatars
• Boosts including a second wind, frozen clock and forgiven slip
• A daily spin and welcome gift

FAIR BY DESIGN
Sign in with Play Games, Google or Apple to carry your account between supported phones. Scores are checked on our servers and each account holds one place on the board. Rulebound tells you when a sign-in changes.

Rulebound contains adverts and optional purchases. No loot boxes: what you buy is what you get.
