Luck isn't random here - you build it. Luck Architect is an idle incremental game about probability: flip weighted coins, roll loaded dice, draw from a deck you shape, and bend the odds until the impossible becomes routine. Start with one coin flip. Weight it, automate it, and watch the numbers climb even while you're offline. Master one kind of chance and the next era opens - six eras so far, each with its own random object and its own way to break it. SIX ERAS OF CHANCE - The Coin: weight a simple heads or tails until it almost never misses - The Dice: stack combos and hot streaks across several dice - The Deck: draw without replacement and decide what stays in the pile - The Wheel: reshape the wedges so the wheel favors you - The Marble Drop: steer marbles through a pegboard and beat the bell curve - The Current: rewire a web of chance where every pulse remembers the last Finished eras keep earning in the background while you build the next. PRESTIGE THAT CHANGES THE RULES Collapse your timeline to earn Axioms. Spend them in the Codex on Laws - permanent rules of probability you can watch fire on screen. Every run is faster and deeper than the last. Changed your mind? Rewrite the Codex and spend your Axioms again. NEW REALITIES, TWISTS AND EXPEDITIONS Seen it all? Start a New Reality. Pick Twists that change how an era plays - a coin that can land on its edge, dice where only pairs pay, a wheel whose wedges grow - and add Burdens for a harder run. Your Legacy carries across Realities. Or set off on an Expedition: a short roguelite run with its own Architect and rules, a Favor at every era door and Trial seals to strike. THE BOOK OF PROOFS Over 130 Proofs to earn: era challenges, secret routes and whole-timeline runs that make you play in a new way. A REAL IDLE GAME - Offline progress: come back to a payout - Auto-Build buys upgrades for you, Fate Autopilot handles your Fate Powers - 200+ upgrades across six Blueprints - Plays offline, no internet needed - Cloud save keeps your progress when you switch phones - Big numbers as letters or scientific notation, Reduce Motion, 7 languages FAIR TO PLAY - No forced ads. Ads are optional bonuses you choose to watch - No paywalls blocking progress - Optional one-time purchases, no subscriptions - Nothing to bet and nothing to lose: you can only build your luck up QUICK ANSWERS Is it idle? Yes. Your engines keep earning while you're away. How long is it? The first eras take hours, the full Codex takes weeks, and Realities, Expeditions and Proofs keep going after that. Do I need internet? No. Sign in only if you want cloud save. Made for fans of idle games, clicker games and incremental games who want more than tapping: a game about probability, automation and upgrades, where every mechanic asks one question - how far can you bend chance before it breaks? Flip the coin. Load the dice. The odds are waiting for their Architect.
