Three classic logic riddles, three games, one app. No ads, no account, no internet needed. Three logic puzzles in one app. Each grew out of a centuries-old riddle; none of them leaves room for luck. KUM · No clock, only sand You have two hourglasses, 4 and 7 minutes. Ring the bell at exactly 9 minutes. There is no clock on screen: time starts when you flip a glass, and you only know how many minutes have passed from the moments the sand runs out. 100 levels, each with different glasses and a different target. KÖPRÜ · Königsberg A river city, land masses, bridges. Cross every bridge exactly once. In 1736 Euler showed that the seven bridges of Königsberg cannot be crossed in one walk, and founded graph theory. The first city is that city; then ninety-nine more river towns. Sometimes the right answer is "impossible", and noticing that is more satisfying than finding a path. TERAZİ · The counterfeit coin One of twelve coins is fake; heavier or lighter, you don't know. You have a balance scale and three weighings. The scale never hides the fake in advance; at every weighing it gives you the answer that challenges you most. 100 levels, from three coins to thirty-nine. HOW TO PLAY The first levels hold your hand: the spot to tap glows, and a line below says why. Nothing to read. Each game remembers your level separately. Free. No ads, no purchases, no account, no internet needed. Turkish and English. From Zaten Games. The games also run in the browser: zaten-games.web.app
