Deep Blue tracks where you are so checkpoints light up as you reach them. It won't work without location access.
Dive through the ice, catch as many fish as you can, and surface safely before the season ends.
Every fish you bring up in time scores automatically — the biggest haul wins.
Your map is double-sided — one side above the ice, one side below. Everything happens at physical checkpoints.
Move to a checkpoint and its button lights up. Tap it to open the checkpoint, then choose an action to make it happen.
Ice Holes, three Seals, the Wise Walrus, and Start/Finish.
Fish — Eels, Cods and Rays — reached by diving through an Ice Hole.
Fish live below the ice. Reach an Ice Hole and tap Dive to go under.
An 8-minute oxygen timer begins the moment you dive. It shows above your score and pulses red as it runs low.
Surface at any Ice Hole, not just the one you came down. Each new dive resets your oxygen.
Underwater checkpoints are fish. Reach one, tap Collect, and it's added to what you're carrying.
Eels are the smallest, then Cods, and Rays are the largest — heavier fish are worth more kilograms.
Catch a fish and it vanishes for the rest of your dive. Grab as many as you dare before you surface.
Take a lesson from the Wise Walrus (see slide 8) and every fish reappears at the same point, but heavier, ready to catch again.
Fish in your paws score the moment you surface through an Ice Hole. There's only one way your fishing trip can go wrong:
Fish score automatically when you surface. Weight values increase as you level up with the Wise Walrus.
| Fish | Level 1 | Level 2 | Level 3 |
|---|---|---|---|
| Eel | 1 | 2 | 4 |
| Cod | 2 | 4 | 8 |
| Ray | 5 | 10 | 12 |
All fish start at Level 1 weights. Take lessons from the Wise Walrus to raise these values for the rest of the game.
Three seals can each be recruited by solving their puzzle. A wrong answer locks that puzzle for 10 seconds. Solve a Seal's puzzle and it starts fishing for you at 0.5kg a minute until the game ends. Then when you visit a Seal, its accumulated catch is added to your score instantly.
Spend banked fish on lessons and every fish becomes worth more (see below). Level 1→2 costs 15kg, Level 2→3 costs 30kg, and each lesson repopulates the fishing points.
| Fish | Level 1 | Level 2 | Level 3 |
|---|---|---|---|
| Eel | 1 | 2 | 4 |
| Cod | 2 | 4 | 8 |
| Ray | 5 | 10 | 12 |
Puzzle answers are a single word, letter or number — for number answers, type 5, not "five".
Get back and check in at the Finish checkpoint within the allowed time to end your game.
Each player must check in at the Finish before time runs out to earn a 15kg bonus, scored automatically. No check-in, no bonus.
Once the game clock ends, no more checkpoints can be reached — no diving, collecting or scoring. The clock sits at the bottom of every screen.
Every surface and every recruited/activated Seal visit adds to your score in real time — what you see at the end is exactly what you earned.
Dive → collect → surface and score. Tap the lit checkpoint at each step.
Get under the ice, fill your paws, and surface before your breath runs out. Every fish you bring up scores automatically. Good luck out there.
Or you drop everything you're carrying.
Their catch scores the moment you arrive.
