Coin Mint Master

Coin Mint Master is an offline history-strategy game about the coinage decisions that made and broke pre-modern economies. You run a royal mint across twelve seeded historical episodes — Rome's third-century denarius, England's Great Debasement, Spain's vellón, the Ottoman akçe, Sweden's copper plate money, Ming cash shortages and more. Every turn you commit an alloy recipe, a planchet weight and a minting quota while war loans, failed harvests, guild petitions, clipped coin and a rival mint undercutting your standard force real trade-offs. A transparent economic model turns those choices into silver content per coin, seigniorage, price level, merchant trust and public unrest. It always shows its work: the Market Square charts Gresham's law as good coin leaves circulation, the Assay Bench verifies any coin deterministically from its mass in air and in water, and the Chronicle prints the arithmetic behind every consequence. Everything is authored and seeded on device — no accounts, no network, no purchases. Any bundled historical coin face or coin you struck in game can be worn as the app icon. FEATURES • Start any of twelve seeded historical episodes — Roman denarius debasement, Henry VIII's Great Debasement, Spanish vellón, the Ottoman akçe, Swedish copper plate money, Ming cash shortage and more — each opening with that era's real fineness table, bullion stock, trade partners and win condition. • Set the planchet recipe on the Mint Floor by dragging silver-to-copper proportions, per-coin weight and the batch quota, then read the predicted coin count, bullion draw, seigniorage and nominal-to-silver ratio before committing the strike. • Verify any coin on the Assay Bench deterministically: enter its mass in air and its mass suspended in water, and the app computes density, converts it to an alloy composition and checks it against that era's legal fineness, weight tolerance, diameter and magnetic class — returning on-standard, debased or counterfeit with the numbers printed. • Answer Reign event cards — a war loan, a failed harvest, a guild petition against clipped coin, a rival mint undercutting your standard, a recoinage proposal — choosing among two to four options whose effects propagate into treasury, prices, trust and unrest. • Watch the Market Square model run as a live chart of silver content against price level across your reign, showing Gresham's law in action as good coin vanishes from circulation and bad coin takes its place. • Open the Chronicle after any turn to read every consequence with its arithmetic, from seigniorage earned to unrest caused, so the economic model is auditable rather than a black box. • Stage a recoinage reform: withdraw debased coin at a stated exchange rate, fund the melt and re-mint cost, and watch trust, prices and hoarding respond over the following turns. • Work through fifty illustrated Money Doctors lesson cards — fineness, seigniorage, Gresham's law, clipping, inflation, bullion flows — each ending in a short check question graded instantly with an explanation. • Wear the age: choose any of twenty-four bundled coin faces, or the face of a coin you struck in game, as the app icon in the Icon Studio, with a live preview and a one-tap revert. Coin Mint Master is a self-contained economic simulation for history and strategy players who want to see the numbers behind every verdict. No accounts, no ads, no in-app purchases, and no network connection required.
