Tessera
Fill each colored region with tiles so its rule holds.
How to play
- The board is split into colored regions, each carrying a rule (sum, all-equal, all-different, parity, and more).
- Place tiles from the rack so every region's rule is satisfied — there's exactly one solution.
- Three daily tiers — Easy, Medium, Hard; solving any tier counts for your streak.
Controls
- Tap a rack tile, then an empty cell to place it.
Techniques
Intersect the rules
Each cell serves its region's rule AND the rack's remaining tiles. List what the rule still allows, strike what the rack can't supply — often one tile remains.
Smallest region first
A two-cell all-different or exact-sum region constrains harder than a five-cell one; settling it cascades into its neighbors.
Uniqueness is a tool
There is exactly one solution. If a placement would leave two interchangeable tiles with no rule to distinguish them, that placement is wrong.
Example
[ A A ] [ B . ]
Fill each cage so its constraint is satisfied.
Tip · Work the smallest, most-constrained regions first.
