Change up!
Make Change. Beat the Clock.
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
Race the clock, make perfect change, and collect every currency in Change Up! Free to play, no login required.
The cashier is waiting. Make the exact change with the fewest coins and notes possible before the register clock runs out.
Change Up! is a fast, minimalist arcade game about the one skill every person needs: making optimal change under pressure. Every round hands you a transaction price and a wallet of coins and notes. Get the right pieces onto the tray, hand over payment, and take back change. The smaller the pile, the higher your score.
FEATURES
Two ways to play — CLASSIC is 20 timed transactions building to a final score; ENDLESS keeps the register open until the clock finally beats you. A real pressure timer — the window shortens as your streak grows, with green/yellow/red zones and a timing bonus for staying sharp. Real-world currencies to master — start in the one you know and unlock the rest by playing well; every currency has its own coins, notes and change-making logic. Score = optimality — you're graded on how close your change is to the mathematically optimal answer, not just on speed, with combo streaks for consecutive optimal transactions. No account, ever — nothing to sign in to. Progress and in-progress rounds save automatically to your device; only the optional leaderboard, rewarded ads and the optional purchase below need a connection. Optional online leaderboard — submit a run under a nickname you choose and compare against global and regional boards. Entirely opt-in; the game is complete without it. Watch a short optional ad for a burst of Change Tokens, or skip ads entirely — every currency is also earnable through play alone. No forced or interstitial ads interrupt a round. One optional one-time purchase (Unlock All) for players who'd rather skip the grind; everything it unlocks is also earnable for free.
Change Up! is built for short, sharp sessions — the kind of round you can finish while the kettle boils, and the kind of high score you'll come back to beat.
