A polar research vessel is waiting for the chests buried under the ice. Tap the squares to smash ice blocks and find the chests — each one is loaded into the ship's hold. Once the hold is full, the ship sails off on its mission.
🔨 Hammer — Every tap spends one. When you run out, earn more with "Play a level".
🧊 Stacked ice — A ×2 or ×3 tag in the corner means that many blocks are frozen in that square. Break the top one and the tag counts down, showing the next number.
📦 Chest — Completely hidden under the ice. Breaking one sends a chain reaction through its neighbours.
💣 Bomb — Wipes out all 8 surrounding squares completely, however many layers they have.
🔗 Pipe Pair (A/B…) — Linked purple blocks. Hit one and its twin takes damage too.
⭐ Jackpot Stage — Every 5th stage is special: thin ice, lots of chests, marked with a star.
