01Three mats and a tray of shapes: plan the fit 
02Bigger boards bring five-cell tiles 
03Shaped mats have their own outline to cover 
04Two-layer mats reveal a second color when sealed 
05Wild clay fits any color 
06Exhibition levels have exactly one solution 
07The Journal tracks stars for every level
Calm by design, tricky by the end.
No timer, no fail screen
There are no lives and no move limit. Undo as often as you like, or restart any time.
One new idea per chapter
100 levels in 10 chapters add new shapes, patches, shaped mats, two-color clay, layers and wild clay.
Color plus symbol
Every color carries its own stamp — circle, stripes, leaf or diamond — so you never rely on hue alone.
A master's hint
From chapter 2, a hint glides a tile into a placement that still completes the board. Hints are earned by playing; the current build sells nothing.
Daily commission
After chapter 1, a daily puzzle that uses only mechanics you've learned. Complete 20 in a month to earn that month's medal.
Plays offline
No account, no ads and no purchases in the current build. Everything stays on your phone.
Ten chapters, ten crafted rewards.
Every chapter teaches one new idea. Clear its finale and a crafted clay object takes its place in the atelier's showcase.
