Keloric

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.
