iPhone

Gridora is a calm, compact logic puzzle about completing a pattern one certain tile at a time. Every number tells you exactly how many of the playable tiles directly above, below, left, and right must be ON. Compare overlapping clues, mark tiles ON or OFF, and let each deduction lead to the next. No diagonals—just clear rules and satisfying logic. PLAY YOUR WAY • Choose Easy, Normal, or Hard Quick Play puzzles • Finish a puzzle in a short break • Undo moves or reset the board whenever you need A PUZZLE EVERY DAY • Play the same Daily Puzzle as everyone else • Track your personal best and Daily streak • Compare completion times on the Daily world ranking LEARN BY PLAYING • A short interactive tutorial teaches the complete rule • Clear tile states make UNKNOWN, ON, and OFF easy to distinguish • English and Korean are supported Gridora is not about avoiding danger. It is about finding what must be true and watching the whole grid fall into place. Online Daily ranking uses an automatically created anonymous account and an optional public nickname. Quick Play and core puzzle play remain available offline. ADVERTISING AND HINTS The app includes ads. Daily Puzzle never forces an interstitial. When a rewarded ad is available, you can choose to watch it for a logical hint. Each applied hint adds 30 seconds to ranking time; time spent watching the ad is excluded from play time. Ads and online ranking require an internet connection. On first launch, the app follows your preferred device language: Korean or English, with English as the fallback. You can change the language in Settings.
