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. ## Key features - Real-time heat simulation - Diverse material properties - Phase-change mechanics - Daily generated puzzles - Endless mode - Level sharing - Universal app support ## Pricing and in-app purchases Base price: Free. **One-time purchases** | Purchase | Price | Type | | --- | --- | --- | | Advanced Pack | $0.99 | one-time | | Extremes Pack | $0.99 | one-time | | Impossible Pack | $0.99 | one-time | | Crucible Pack | $0.99 | one-time | | Forge Pack | $0.99 | one-time | ## Frequently asked questions about Keloric ### What is Keloric?

Every level validator-solvable. ### 1.10 — 2026-05-15 1.10 — bug fixes and polish. • Replaying a past Daily Challenge now keeps the result in your history without resetting today's streak. • Level Select stars update the moment you finish a level — no more backing out and coming back in to see your new badge. • Older save records missing tick timing now get upgraded the next time you finish that level at the same star count. • Imported community levels go through stricter validation and won't collide with built-in level IDs. • Hardening against rare crash from malformed level data. ### 1.3 — 2026-05-08 THE IMPOSSIBLE PACK Twenty new levels for solvers who already mastered Extremes. The new ceiling. What makes a puzzle Impossible: • RAZOR BANDS — Most targets sit inside ±5°C windows. A few drop to ±3°C. There is no comfortable margin. • TIME LIMITS ON EVERY LEVEL — 90 to 180 seconds. Stop and think, but don't think too long. • NO SLACK — Par equals your budget. Every source has to land in exactly the right cell. • COUNTERINTUITIVE LAYOUTS — Walled chambers with single gaps, wooden throttles in series, glass corridors that bleed heat at rates the player has to learn the hard way. Twenty themes: Hairpin, Knife Edge, Frostfire, Echo, Pinch, Glass Cathedral, Trinity, Capacity, Polar Twins, Microscope, Paradox, Solar Flare, Thermal Vault, Convection, Endless Loop, Razor Wire, Cold Snap, Equilibrium 2, Exact Science, Apex Final. Every level was tested by the same cellular-automaton solver that ships inside the app. If the validator can solve it, you can — but that's not a promise about how long it will take. WHO THIS PACK IS FOR If you've already three-starred Extremes, this is the next step. If you haven't, save your money for now and finish Extremes first. This pack does not teach. It tests. PRICING Impossible Pack is a one-time $3.99 unlock. Premium tier above Advanced and Extremes ($2.99 each). No subscription. No ads. Yours forever. PLUS THE DAILY CHALLENGE Still free. Still a fresh puzzle every day, same for every player worldwide. Now harder on weekends than ever. ### 1.2 — 2026-05-07 SIXTEEN NEW LEVELS The biggest content drop since launch. Every existing pack gets bigger. • FUNDAMENTALS (free pack) — 6 new levels: Counterbalance, Insulate, Funnel, Twin Peaks, Cold Comfort, Equilibrium. The free tier is now 18 levels, up from 12. • ADVANCED — 5 new levels: Crossover, Bottleneck Redux, Quad Targets, Glass Maze, Final Standoff. Now 20 levels. • EXTREMES — 5 new levels: Razor 2, Triple Threat, Cold War, Zero Margin, Apex. Now 20 levels. If you already own Advanced or Extremes, the new levels are added to your library automatically. No extra purchase. Consider it a thank-you for being an early supporter. NEW THEMES, NEW MECHANICS • Counterbalance teaches you how hot and cold can cancel out to land a mid-temperature target. • Cold Comfort is the first all-cold puzzle in Fundamentals — glass throttling cold flow into a narrow comfort band. • Crossover puts a hot path and a cold path through the same cell, forcing precise placement. • Apex (Extremes) sets up four isolated corridors. Four sources, four bands, four chances to misplace. • Equilibrium is the new Fundamentals finale — two chambers, two targets, two sources, no slack. ALL VALIDATED SOLVABLE Every new level is run through the same cellular-automaton solver that ships with the app. If the validator can solve it, you can. No soft puzzles. No bugs hiding in the layout.
