Relaxation & Logic
Velvet Domino
Choose a domino. Match its two numbers.
Each domino covers two squares. Choose a tile, turn it if needed, and place it where both numbers match. A hands-on lesson shows you every control on a tiny board before the full puzzle begins. The optional Sum room asks you to reach the totals along each row and column.

Made for a proper session.
- A tiny-board lesson teaches choosing, turning, reversing and placing a tile, then gives you a small independent puzzle
- Two distinct rooms: exact cell-number matching, or row/column sum reasoning with sparse printed clues
- 24 seeded tables per collection, four chapters, three complexities and a daily collection
- Boards grow from 2×4 to 4×6; mixed horizontal and vertical dominoes, zeroes and repeated values deepen the logic
- Rotate and flip each two-square tile; touch and keyboard selection, free undo, clear and tile return
- Any arrangement satisfying the full constraints is accepted; every generator reference solution is verified
- Optional reference steps rebuild a disclosed reference layout; assistance and unsuccessful-check costs remain visible
- Separate guided practice preserves the active collection, with no countdown or speed bonus
- English and Simplified Chinese, music and volume controls, resumable checkpoints and comparable completed records
A recreational logic game. Suggested from about age 8 with adult support where helpful. Play records describe this game and are not a clinical assessment. Generated tables vary, so comparisons are personal play records rather than standardised measures.
