How to play
You complete Thermometers when all row and column totals match and each thermometer's filled cells form one contiguous prefix beginning at the bulb. The full Thermometers position determines the outcome; visual shortcuts never replace the documented Thermometers terminal rule.
- Thermometers begins with a grid partitioned into bent or straight thermometers with a bulb direction and numeric fill counts beside every row and column. The Thermometers deal identity and Thermometers championship rules v1 are stored together. Restarting Thermometers reproduces this opening exactly.
- During Thermometers, you mark a cell filled or empty, but any filled thermometer segment forces every earlier segment toward its bulb to be filled. The Thermometers engine rejects profile violations, unavailable material, and every action attempted after Thermometers reaches a terminal result.

Strategy tips
- A reliable Thermometers plan is to use completed line totals to cap intersecting thermometers and propagate every forced prefix back to its bulb. A Thermometers hint is legal and deterministic. The next Thermometers hint exposes one bounded action; it never claims a forced Thermometers win.
- A costly Thermometers mistake is to fill a segment beyond an empty segment closer to the bulb; temperature cannot skip space inside one thermometer. Undo supports studying that Thermometers decision, while restart preserves the original seeded Thermometers opening.
- In the Thermometers endgame, translate each remaining line deficit into a unique thermometer prefix length and verify both directional totals. Check every remaining Thermometers action before committing because its terminal rule is enforced immediately.
