About this game

Numbers are your map. Hearts are your budget.

Tidecipher is a minesweeper-style dungeon puzzle. Every revealed number adds up the power of creatures hidden in the eight surrounding tiles. Read the clues and decide which fights you can survive.

A Power 13 Abyss Dragon waits at the center of the first 13×10 board. Battles cost hearts and grant experience. Exactly zero hearts is still safe. Fill the experience crystal and level up to restore your hearts.

Choose one tool for each depth, with two uses: SONAR counts enemies in a 2×2 area, PERISCOPE reveals a tile without combat, and SHIELD reduces damage in your next fight. Creature placement patterns give you more clues to work with.

Boss hits land with a deep impact sound and a shaking board. Defeat the dragon, then choose DIVE DEEPER or keep exploring the current floor. The next depth brings a new board and a fresh tool choice.

The game, settings and tutorial support English, Korean and Japanese. No account is needed; settings and records stay on your device.

Free with ads. DIVE DEEPER shows an interstitial before each descent. Ads require an internet connection; if an ad cannot load, the current floor stays available and you can retry. One optional non-consumable purchase permanently removes all ads and lets you descend directly. Purchases can be restored from Settings.

Tidecipher's gameplay format is inspired by DragonSweeper by Daniel Benmergui, with its own name, art, audio, and writing.
Read clues, choose your tools, and descend into a minesweeper-style dungeon.
