A Push-Your-Luck Game Inside a Computer

Coreheat is a push your luck game and an overclocking game set in a city on a motherboard. You are Milli Ampere, a thumbnail-sized thermal engineer who surfs a decommissioned CPU heatsink down the copper heat-pipes of Mainboard City. Overclock a district and it pays you in compute cycles — and the heat gauge climbs. Bank your haul, or push one more district and risk a thermal meltdown that melts the whole 2.5D board like wax and takes every unbanked cycle with it.

Only 3 of the 8 districts are powered at a time. The grid picks which — not you. The Core, the jackpot at the city's heart, might light up while you are stone cold. Or at 88 heat, with everything you have earned still on the table.

What it is:

A game inside a computer — an isometric motherboard city game of capacitor towers and gold trace-streets
Honest push-your-luck: every district prints its heat range and payout range before you commit. You know the odds, never the roll
3 of 8 powered. You do not choose the order — the one thing that makes "risk it or bank it" a real question
A thermal meltdown game where losing is the best part: the city slumps like a birthday candle, and one traffic light keeps blinking in the puddle
An idle arcade hybrid — City Works computes while the app is closed, then funds your next run. The runs stay the star
The Night Shift: a daily challenge game like Wordle, one seeded run per day, identical for everyone on Earth, shared as an emoji grid
An offline idle game — no wifi, no account, no server, no ads. Nothing leaves your phone

Coming soon to the App Store & Google Play.

Coreheat gameplay — a shift in progress on Mainboard City: the heat gauge at 75 of 100, three district signs lit with their heat and payout ranges, PCIe Boulevard greyed out and marked UNPOWERED, a cyan chain snaking through the districts already overclocked, and a gold BANK button holding 906 cycles

How It Works

🎲 One Decision, Over and Over

Overclock a district, or bank and end the shift. Each district's sign shows its heat range and its payout range before you touch it — you always know the odds and never the roll. Roll high and the gauge jumps. Cross 100 and the city melts. There is no hidden rubber-banding, ever: the dice are audited in our own tests, and the ranges you read are the exact ranges the game rolls inside.

⚡ The Grid Picks. You Don't.

Only three of the eight districts are powered at any moment; the other five sit dark. Take a powered one and the grid lights another in its place. So you cannot cherry-pick the fat districts while you are safe and cold — and a district you refuse keeps its slot, glowering at you for the rest of the shift. If you love games like Flip 7, this is the mechanic you came for: you know the deck, never the shuffle.

🔥 The Meltdown Is the Marketing

Cross the line and the gauge glass cracks. Every window in the city turns red in a wave. Then the board sags — capacitor towers fold like birthday candles, RAM Heights droops into an accordion, and The Core's heatsink ziggurat slides off sideways with a low brass groan. Four and a half seconds later it is a glossy, steaming wax puddle with one traffic light still blinking in it. Then it reboots. Your cycles do not.

🛣️ Routing Is the Skill

Districts sit on real trace-streets. Overclock one next door to the last and you extend your chain — up to a 2× banking multiplier on a full eight-district snake, which almost nobody ever gets, because the grid has to cooperate. Coolant canisters sit on the streets themselves, so taking the long way round to grab one costs nothing but time. A lovely tension.

🏙️ City Works — It Computes While You Sleep

Banked cycles fund ten infrastructure upgrades that keep earning while the app is closed, capped at eight hours so two visits a day is exactly right. The city you come back to is visibly bigger and brighter than the one you left. It is an idle arcade hybrid tuned on purpose so that ~70% of everything you ever earn comes from playing, not waiting. The idle city funds your ambition; it never replaces your skill.

🌙 The Night Shift — One Seed, One Earth

One seeded run per calendar day, generated from the date itself: the same districts, the same power order, the same dice, and the same daily modifier for every engineer alive today. One attempt, no retries, no rewind. Share it as a spoiler-free emoji grid — 🟩🟩🟨🟥 — and find out who banked and who got greedy. It works with no wifi, like everything else here.

A Look Inside

Coreheat's thermal meltdown — the heat gauge reads 111 of 100 and the whole isometric motherboard city is mid-slump, buildings sagging and smearing downward like wax under a red alarm vignette, with one traffic light still blinking in the puddle — The meltdown — you pushed one more district

Coreheat's home screen — Mainboard City rendered as a living isometric diorama of capacitor towers and glowing gold trace-streets, with the banked cycle balance, the no-meltdown streak, a START SHIFT button and the Night Shift daily card — Mainboard City — the city grows every time you bank

Coreheat's City Works screen — the ten-upgrade idle tree with levels, cycles-per-minute rates and costs, showing the Idle Clock Governor, Thermal Paste Refresh, Case Fan Array, Trace Repaving and Cache Prefetchers — City Works — the idle layer that funds the arcade

Coreheat's Night Shift screen — the daily seeded challenge showing tonight's number, the seed derived from the local date, and the revealed daily modifier card reading SURGE PROTECTOR: meltdown threshold rises to 110 — The Night Shift — same board, same dice, everywhere

Coreheat's unlock screen laid out as a departures board — four expansion boards at $3.99 each with their twists listed, and the All-Access bundle at $9.99 down from $19.95, with the promise that money never buys power — Never pay for power — only for places and style

Privacy First — Your City Stays on the Phone

Coreheat is built local-first. Here's exactly how it works:

No account, no cloud, no server. You don't sign up or log in. There is no backend that receives your progress — nothing to leak, and nothing to fail on an update or a new phone.
Your save never leaves the device. Your cycles, your city, your records, your streaks and your settings live only in a small local file on your phone.
The game is fully offline. Every board ships inside the app. Even the Night Shift is generated from the date itself, on-device — the daily challenge is identical worldwide with no server involved at all.
Every board is already on your phone. An unlock is a local entitlement check, not a download. Nothing is streamed, and nothing phones home to decide where you may ride.
One billing helper. The only data that ever leaves your phone is purchase data, handled by Apple, Google and RevenueCat to validate and restore your optional one-time purchases. They never receive your gameplay. Anonymous crash and usage diagnostics help us fix bugs, and are never linked to you.
