Senbon Kumiki: Wood Puzzle

Make room, then free every piece. Try 12 introduction puzzles with unlimited Undo, then unlock up to 10 new puzzles a day free from a collection of 72.

One piece looks ready to leave. But what will it block next?

Senbon Kumiki is a 3D wooden puzzle about finding the right order. Tap a piece to move it along its arrow. Read the shapes and overlapping layers, then work out how to free them all.

MAKE ROOM BEFORE YOU REMOVE A piece that cannot come out yet may still move partway. Shift it to open a path, free another piece, then return to the first. Find the sequence that fits together, with no timer rushing your next move.

LEARN BY TRYING The 12 free introduction puzzles progress from quick successes to thinking ahead. Undo as often as you like: try another order, or solve without Undo if you prefer. The collection contains 72 puzzles across six stages of 12, from Introduction to Stage 5.

UNLOCK UP TO 10 PUZZLES A DAY Beyond Introduction, unlock up to 10 new puzzles a day for free. The allowance resets at 00:00 UTC and does not carry over. Unlocked puzzles stay available to retry, and restarting a puzzle is always free. Three daily picks and six weekly picks offer selections from the included collection. Opening a locked pick uses the same daily allowance.

UNDO AND RETHINK Beyond Introduction, unlock Undo through optional rewarded ads or one-time passes. • Watch an ad for unlimited Undo until you clear your current puzzle, including after a restart. • Choose a different ad to unlock 5 more puzzles, with unlimited Undo in those five. Rewards require completing the ad and its stated conditions. Ads may not always be available.

CHOOSE A ONE-TIME PASS • Unlimited Undo Pass: unlimited Undo in the current collection. The daily puzzle allowance still applies. • Puzzle Access Pass: remove the daily unlock limit for the current collection. Undo is not included. • Full Pass: both benefits together. These are one-time purchases, with no subscription. If you own one of the separate passes, you can buy only the missing one. See the purchase screen for prices. Future paid collections are not included.

Wooden sounds and puzzle-clear animations accompany your play. Turn sound on or off and choose reduced motion in the settings. Available in English and Japanese.
