No revenue estimate for the App Store: Apple publishes no install counts, and its star-rating counts don't calibrate to sales the way Steam's written reviews do. Reviews and prices only.
You play as a fearless duck who battles enemies not with brute force, but with math smarts. The rules are simple but addictive: - Pick from shuffled number cards and combine them to make 10. - Each correct match becomes your attack to damage enemies. - Defeat foes, earn XP, and level up your duck! Every level-up lets you choose from 3 unique upgrades. Each run is different, and your choices shape the way your duck fights. Sharpen your mind, master the numbers, and guide your duck to victory!
