What is Fleetoku?
A free Queens-style region-logic puzzle with pirate ships, colorful waters, and no numbers to enter.
Fleetoku turns the familiar Queens logic puzzle into a pirate fleet challenge. Each board is split into colored sea regions, and your job is to place exactly one ship in every row, every column, and every region.
Ships cannot touch, even at the corners. That extra rule links nearby cells and makes each placement useful: one ship can eliminate options across a row, a column, a region, and the surrounding diagonals.
How to play Fleetoku
Use crosses to record impossible cells, then place ships only where every rule still fits.
Place exactly one pirate ship in each row and exactly one in each column.
Place exactly one ship inside every colored sea region.
Keep ships apart. Two ships may not touch horizontally, vertically, or diagonally.
Tap or drag to mark crosses. Double tap a legal cell to place a ship; use Undo or Hint when needed.
Common Fleetoku mistakes to avoid
Do not treat the colored regions as decoration. A board is incomplete if a row and column look correct but one sea region contains two ships or none. Check all three one-ship rules together before confirming a placement.
Also mark every diagonal neighbor after placing a ship. Missing one corner can leave a false candidate on the board. If progress stops, recheck your crosses instead of guessing—a mistaken cross can hide the only legal cell.
Fleetoku strategy for beginners
The fastest route is usually elimination, not guessing.
Compare regions with lines
If every candidate in a region lies in one row or column, the ship for that line must come from the region, so other cells on that line can be crossed out.
Check diagonal neighbors
After placing a ship, mark all touching cells immediately. Corner exclusions are easy to miss and often reveal the next forced move.
A reliable step-by-step solving method
First mark the row, column, region, and neighboring cells around every confirmed ship. Next, scan for a row, column, or colored region with only one legal cell left. Place that forced ship and repeat the same checks.
When no single cell is forced, compare overlapping constraints. A region whose candidates all share one line can eliminate the rest of that line, even before you know the exact ship position. This cycle solves the board logically without trial and error.
210 levels across three difficulties
Build confidence on compact boards, then progress to larger region-logic puzzles.
50 Normal levels introduce the rules on approachable boards.
75 Hard levels add larger grids and tighter region interactions.
85 Ultra levels run up to 11×11 for experienced logic-puzzle players.
The first 10 levels in each difficulty are open; finishing each boundary unlocks 5 more.
How Fleetoku difficulty changes
Normal boards favor visible single-cell deductions and smaller grids. Hard levels make rows, columns, and regions interact across more of the board. Ultra levels use the largest grids and longer deduction chains, so careful cross marking matters more than speed.
Every included board is fixed rather than randomly generated during play, and a solver verifies that it has exactly one valid solution. Your completed levels and current session are saved locally in this browser so you can return to the campaign later.
Fleetoku FAQ
Quick answers before you begin a voyage.
Is Fleetoku a Sudoku game?
It is a Sudoku-style logic puzzle, but it uses ships and colored regions instead of numbers. The one-per-row, one-per-column, and one-per-region constraints drive every deduction.
Is Fleetoku free to play online?
Yes. All 210 levels run in your browser with no download or account required.
How is Fleetoku different from a Queens puzzle?
It uses the same core region-logic rules found in Queens-style puzzles, but presents them as a pirate fleet campaign with ships, smart crosses, hints, and progressive difficulty.
Can I play Fleetoku on a phone?
Yes. The board supports touch gestures: tap to mark, drag to paint or erase crosses, and double tap to place a ship.
Does Fleetoku save my progress?
Yes. Completed levels and your current board are stored locally in your browser. No account is needed, but progress does not automatically move to another browser or device, and clearing browser storage can remove it.
Does every Fleetoku level have a unique solution?
Yes. All 210 fixed boards are checked by a solver to confirm that the colored regions are connected and that exactly one ship arrangement satisfies every rule.
What help is available if I get stuck?
Use Undo to reverse moves, Smart crosses to mark exclusions around confirmed ships, or Hint to focus on a constrained row, column, or region. A later hint can reveal one safe ship position per level.
