Draw your route to the treasure

How a puzzle works

Your ship starts on one side of the board and the treasure waits somewhere on the other. You drag the ship from square to square to draw its route. The numbers along the top and the left side say how many squares of that column or row the route uses. When every number fits and the ship reaches the chest, the lid springs open and the coins come out.

There is always one right route, and you never need to guess. Rocks, wrecks and tentacles block the way, so each board becomes a little chain of reasoning: this row needs only one square, so the route cannot turn here; that column is full, so the ship must go around. Tap a square to mark it with a cross when you are sure the route will not pass it.

Five worlds, each with its own rule

You start on the open sea and sail on through the ice sea, the volcano island, the jungle river and the ghost sea. Every world has thirty puzzles and its own water, its own islands and its own pieces on the board. A walrus lies on the ice, a crocodile waits in the river and ghost ships drift through the fog.

Each new world adds one rule that changes how you think. In the ice sea a frozen piece of route shows exactly how your ship must pass. On the volcano island the lava only lets you sail straight through. In the jungle a whirlpool makes you turn, and in the ghost sea some numbers hide in the fog, so the others have to show you the way. A world opens once you have solved the one before it.

A new puzzle every day

Next to the worlds there is the puzzle of the day: one fresh board, the same for everybody that day, that never costs a life. Solve it on consecutive days to build your streak, and earn a compass and coins along the way.

Help when you need it

Stuck? The check is free and shows where your route stopped being right, without giving the answer away. A compass lays down the next right piece of route for you. You earn compasses by playing: one for every ten puzzles you solve and two for every world you finish.

A wrong number costs one of your three lives, and lives come back on their own over time. Playing a puzzle you already solved is always free, so you can replay your favourites whenever you like.

Your own ship

In the harbour you rig your ship the way you like it. Pick a sail, a flag and a hull, and pay for them with the coins you earn by solving puzzles. Your ship then sails with you on every board and across the map of the worlds.

Free, calm and without ads

All five worlds and all 150 puzzles are free to play. There are no ads, no timers that rush you and nothing that tracks you across other apps. If you want to support the game, you can buy coins, a handful of compasses or the shipmate pack, but you never have to. Piradoku is made for young and old, in Dutch, English, German, French, Spanish, Japanese and Portuguese.
