Find the ghosts hiding on the board, using nothing but the numbers. Nothing is left to luck.

👻Goal

Find every ghost (the Keepyboos) hiding in the board to clear the round.

🔢Reading the numbers

Edge numbers show how many ghosts hide in that row or column. A number inside a cell counts the ghosts in its 8 surrounding cells. To clear a round, every one of these conditions must be satisfied.

👆Controls

Tap once to mark × (no ghost here). Double-tap quickly to reveal a ghost. A wrong reveal costs 1 LIFE — lose all 3 and it's game over. Long-press to toggle a 📌 pin — a marker for what-if reasoning that never affects the game. Tap any row, column or board number to see how many ghosts are still hiding there.

⚡Opening in one go

When a condition is satisfied, the remaining cells in its range are crossed off automatically. Satisfy several conditions at once and more cells open together.

⭐Score & stars

Stars add up from three independent goals: one for clearing, one for a no-miss clear (full LIFE), and one for reaching the round's target score.

🧮Scoring basics

Each tap scores 100 + opened cells × conditions completed × 50. The full exact rules and a worked example are in Settings > "Scoring".

💡Hints

Up to 3 per round. A hint highlights cells that can be proven, and the conditions that prove them. Each hint costs one video ad (free if you own Remove Ads). Using a hint drops the 👑 one rank — the same as a miss; no big crown. The 🧠 mark is still earned while every reveal can be proven from confirmed information alone, but a hinted first attempt does not count toward your Logic Rating.

🔁After you clear: a second puzzle

The first time through, a round is a deduction puzzle: where are the ghosts hiding? Clear it with the 🧠 mark and the same round comes back as a different puzzle. The ghosts now show faintly, and the question becomes: in what order should you catch them? On the same board the order can change the score several times over. Find the best order for 💎, or hold the score to the lowest possible for 💀. The faint number on each ghost is the points it would give if you caught it right now. (You can turn the faint display off in Settings. While it is on, the round does not count toward the 👑 crown.)

💎💎 Hints

In a round you have already cleared with 🧠, the Hint button becomes the 💎 Hint. First: the 💎 light, which tells you after every move whether your order can still reach the best score. Second: it opens every ghost whose timing never changes the score, leaving only the ones whose order matters. Third: if the light goes out, it takes you back to the board just before it did. None of them tells you the answer. They last while you stay in the round, even if you reset.

🏆Achievements

👑 Crown — upgraded by clearing without hints or misses. 🧠 Brain — every reveal provable at the moment you tap. From your next visit, brain-cleared rounds faintly show the solution, enabling planned runs for the optimal score (can be turned off in Settings). 💎 Diamond — a no-miss clear that reaches the proven best score. 💀 Skull — a no-miss clear held down to the proven minimum score.

💎Chasing the diamond and the skull

The number of cells that open in a round never changes with the order you find the ghosts in. The same cells score more when a single tap opens many of them and completes several conditions at once. For 💎, complete as many conditions at once as you can; for 💀, complete them one at a time. Both require a no-miss clear.
