KELORIC is a thermal-physics puzzle game. You don't draw paths. You don't push blocks. You place heat and cold sources on a grid of materials — metal, glass, wood, ice, wax, walls — and let the heat actually flow. Every cell is simulated tick by tick. A metal corridor spreads heat fast. Wood throttles it. A wall stops it dead. An ice pack absorbs heat, holds the path closed, and then — once enough energy has melted it — turns into water and lets the heat through. Wax does the same trick at 50°C, then floods heat through faster than metal. Place your sources, watch the temperature spread, and hold every target inside its band long enough to win. — REAL PHYSICS — A cellular-automaton solver drives every cell on the board. Heat moves between neighbors based on conductivity. Materials with high heat capacity warm slowly. Phase-change cells stall the system, absorbing latent heat before transforming. There are no hidden rules: what you see in the colors is what the simulation is doing. — SIX PACKS · 178 PUZZLES — • Fundamentals (free) — 28 levels including a phase-change introduction. Learn the mechanics step by step. • Advanced — 25 levels of tighter routes and narrower target bands. • Extremes — 25 levels with ±10°C bands and unforgiving budgets. • Impossible — 25 levels for players who beat the rest and want more. • Crucible — 25 levels built around melting ice. Heat dams, buffer races, slow burns, cascading melts. • Forge — 20 levels built around wax. Solid wax blocks heat like wood. Heat it to 50°C and it melts into molten wax — which conducts heat faster than metal. Burn through gates, time your melts, mix wax with ice for compound puzzles. — DAILY + ENDLESS — A new puzzle every day, generated from the date. Build a streak. One missed day per month is forgiven. Endless mode generates infinite puzzles with rising difficulty. How far can you push your streak before a level breaks you? — GAME CENTER — Fourteen achievements. Two leaderboards. Compete on Endless best streak and Daily current streak. — BUILT FOR iPHONE AND iPAD — Universal layout. Portrait on iPhone, all-orientation on iPad. Drag to paint, double-tap to erase. CloudKit syncs your progress across devices. — NO ADS. NO ENERGY METER. NO TARGETED TRACKING. — Buy a pack once, own it forever. Free packs are genuinely free — no premium currency, no daily limits. Optional anonymous gameplay analytics help us tune level difficulty (opt-out in Settings → Privacy). No personal data is collected. — SHARE YOUR FAVORITES — Export any level you've played as a `.keloric` file or paste-code. Import others' levels straight into the app from a URL or AirDrop. If you liked Hexcells, Opus Magnum, SpaceChem, or Zachtronics games, Keloric is built in that lineage — but with a physics core that gives every puzzle a fingerprint-unique solution path.
