Mr Bit

Mr Bit

A calm, elegant HEYAWAKE logic puzzle on warm washi paper with soft sumi-ink walls. The grid is divided into rooms by bold borders, and your job is to paint exactly the right walls so every rule falls into place. Pure deduction, no luck, no timers breathing down your neck - just a few quiet minutes of tidy thinking whenever you want them.

HOW IT PLAYS
Tap a cell once to paint it as a wall, tap again to drop an X note on a cell you think stays empty, and tap a third time to clear it. A room that shows a number must contain exactly that many painted walls - rooms with no number are free. Painted walls may never sit directly side by side. Every unpainted cell must stay connected in one single empty area. And no straight horizontal or vertical line of empty cells may run through more than two rooms. Satisfy all of that at once and the puzzle is solved.

ALWAYS SOLVABLE, ALWAYS UNIQUE
Every level is built from a real valid solution and then verified by the game's own solver to have exactly ONE answer. No guessing, no dead ends by design - if you reason carefully, the solution is always there and it is always the only one.

TEN ROOMS, GROWING CHALLENGE
Ten deterministic levels that grow from a gentle four-by-four to a dense eight-by-eight manor, adding more rooms, richer number clues and tighter walls as you climb. The same level always plays the same, so you can learn its shape and beat your best.

STARS, COINS AND A SHOP
Finish clean and under par time for up to three stars, and earn coins on every level. Spend them in the shop and claim a small daily gift. Everything is earned in-game - no pay-to-win.

MADE TO RELAX
Washi-cream board, crisp ink walls and no pressure - easy to learn, quietly satisfying to master, one thumb at a time.
