About Nurikabe Puzzle - Atollo
Atollo is a nurikabe puzzle game with three new daily charts. Every nurikabe puzzle starts as a grid of numbers in open water: mark land and sea until each number sits on an island of exactly that size.
Nurikabe is one of the classic Japanese logic puzzles, like Sudoku. No guessing and no math, just four clear rules and the moment when the last island falls into place.
THE RULES
• Each number is the size of its island
• Islands never touch side by side
• All water is connected
• No 2×2 pools of water
THREE DAILY CHARTS
• Lagoon 6×6, Reef 8×8 and Open Sea 10×10
• New charts every day, the same for everyone worldwide, each with its own number
• Share your result as a short text with your times and a store link, without spoilers
ONE SOLUTION, ALWAYS FAIR
• Every chart is proven to have exactly one solution by our own solver
• A chart counts as solved as soon as it follows the rules, it is never compared against one stored answer only
• A hint fills in the next logical step and names the rule that makes it certain
• Check marks the cells that do not match the solution
MADE FOR YOUR PHONE
• Swipe to paint many cells in one go, mark land with dots
• Unlimited undo and redo
• A coastline appears around every finished island
• Live warning for a 2×2 pool or an island that grew too big
• Day chart and night chart appearance, English and German
• Plays offline, no account needed
FREE PLAY AND STREAKS
• 900 free puzzles in 6×6, 8×8 and 10×10 next to the daily charts
• Day streak, statistics and best times
• Optional daily reminder at 9:00 when the new charts are ready
THE FREE VERSION: FREE WITH ADS
• 3 daily charts every day and all 900 free play puzzles
• 2 hints a day and 1 check per puzzle
• Out of hints? Watch an optional short video for one more hint or check, and after a solved chart a video gives you +2 hints
• Ads from our advertising partners: a banner at the bottom of the home screen, now and then a full-screen ad between two charts and when you return after a longer break, never in the middle of a puzzle
