About Kanoodle Puzzle
Kanoodle is a spatial reasoning puzzle inspired by the popular physical puzzle game of the same name. The goal is to fit a set of uniquely shaped polyomino pieces (shapes made of connected squares) into a rectangular grid so that every cell is filled with no gaps and no overlapping.

Solve Kanoodle puzzles free online: a new Daily Puzzle every day, a Timed mode and four levels. Fit all 12 pieces into the 5x11 board. No sign-up.
How to use
- Pick a mode: Puzzle (the classic Kanoodle challenge: some pieces are already on the board and you fit the rest), Daily (one new puzzle a day, the same board for everyone), Timed (race the clock and beat your best time), or Free (an empty board to fill any way you like).
- In Puzzle and Timed modes, choose a level: Starter leaves 1-2 pieces for you to place, Junior 3-4, Expert 5-7 and Master 8-12 (sometimes the whole board). Pre-placed pieces are striped and stay put. The Daily puzzle sets its own level, climbing from Junior early in the week to Master at the weekend.
- Pick up a piece by clicking or tapping it in the tray, or drag it straight onto the board. On a computer an outline follows your pointer and turns red where the piece will not fit; click to drop it. On a phone, tap the board to preview the spot, then tap the preview again to place it.
- Use Rotate (or press R) to turn the piece 90 degrees and Flip (or F) to mirror it. Clicking the selected piece in the tray rotates it too. Most pieces have 4 or 8 distinct orientations, and finding the right one is often the entire puzzle.
- Changed your mind? Drag or tap any piece you placed to pick it back up, press Undo (Ctrl+Z) to take back your last move, or Clear to lift all of your pieces. The status bar shows how many pieces are left.
- Stuck? Hint picks up a piece, turns it the right way and shows where it fits, worked out from your current board. Hints are counted, and in Timed and Daily modes each one adds 30 seconds to your time. Strategy tip: place the most awkward pieces (the plus, the long bar, tight S-shapes) first, because they have the fewest legal spots.
- Fill all 55 cells to win. Every puzzle is cut from a real solved board, so it always has at least one solution. Your solve count per level, best Timed times and Daily streak are saved in your browser with no account needed, and Copy result lets you share a Daily or Timed finish.
Frequently asked questions
What is a Kanoodle puzzle?
Kanoodle is a spatial reasoning puzzle inspired by the popular physical puzzle game of the same name. The goal is to fit a set of uniquely shaped polyomino pieces (shapes made of connected squares) into a rectangular grid so that every cell is filled with no gaps and no overlapping. Each piece can be rotated and flipped to find the right orientation. The puzzle exercises spatial visualization, logical deduction, and trial-and-error problem solving. It is similar in spirit to classic pentomino puzzles and tangrams.
How many puzzles are available?
Puzzle and Timed modes generate a fresh board every time you press New puzzle, across four difficulty levels, so you will never run out. Easier levels pre-place most pieces and leave you a small set to fit, which is ideal for learning the mechanics. Master can leave the whole board empty, which takes far more planning. The Daily mode adds one shared puzzle each day. Every puzzle is cut from a real solved board, so it is always solvable, and many puzzles have more than one solution.
Is there a daily Kanoodle puzzle?
Yes. Daily mode serves one new puzzle every day, and everyone who plays on the same date gets the same board. Difficulty climbs through the week: Junior on Monday and Tuesday, Expert from Wednesday to Friday, and Master at the weekend. Solve it on consecutive days to build a streak. Your streak, times and best streak are stored in your browser only, so there is nothing to sign up for. When you finish, Copy result puts your time and hint count on the clipboard so you can share it.
How does Timed mode work?
The clock starts when you pick up your first piece and pauses if you switch to another tab. Each hint adds 30 seconds. You earn up to three stars based on your time for the level (on Starter, three stars for 30 seconds or less and two for a minute or less; the bar rises with each level), and your best time for each level is saved in your browser.
What are some tips for solving Kanoodle puzzles?
Start with the most unusually shaped pieces first — pieces with odd bends or protruding cells have fewer possible placements on the board, so placing them early narrows down the remaining possibilities. Work from corners and edges inward, since pieces placed along the border are more constrained and easier to reason about. Avoid leaving isolated single-cell gaps early in the solve, because very few pieces can fill a lone empty cell. If you get stuck, try removing the last two or three pieces and re-approaching with different orientations.
What are polyominoes?
Polyominoes are geometric shapes formed by joining unit squares edge to edge. A domino (two squares) and tetromino (four squares, like Tetris pieces) are common examples. Kanoodle typically uses pentominoes (five squares each) and smaller polyominoes. There are exactly 12 distinct pentomino shapes (not counting rotations and reflections), and they have fascinated mathematicians and puzzle designers since the 1950s when Solomon Golomb popularized them. Pentomino tiling puzzles are NP-complete in the general case, meaning there is no known shortcut — you genuinely need to think through each placement.
Is Kanoodle good for brain training?
Yes — Kanoodle puzzles exercise several cognitive skills simultaneously. Spatial reasoning (visualizing how shapes fit together), working memory (tracking which pieces remain and what gaps exist), planning (thinking multiple placements ahead), and mental rotation (imagining a piece flipped or turned) are all engaged during play. Studies on spatial puzzle games suggest they can improve spatial visualization skills over time, which transfer to fields like mathematics, engineering, and architecture. The puzzles are suitable for all ages, from children developing spatial awareness to adults keeping their minds sharp.
How is this different from Tetris?
Tetris and Kanoodle both use polyomino shapes, but the gameplay is completely different. Tetris is a real-time action game where pieces fall from the top and you must quickly rotate and place them under time pressure. Kanoodle is a turn-based logic puzzle with no time limit (unless you choose Timed mode) — you have all the pieces available from the start and must figure out how to fit them all into the board simultaneously. Kanoodle is closer to a jigsaw puzzle than an arcade game, rewarding patience and spatial planning rather than reflexes.
