35 seconds. 11 puzzle types. One judgmental otter. How high can you climb on Bob's Rank? No ads, no IAP — just pure pattern-solving fun. Bob has seen 600 years of mail pass through his post office. Now he wants to see how sharp YOU are. Bob's Riddles is a cozy, fast-paced pattern puzzle. You get 35 seconds. Bob gives you stamp sequences — spot the rule, pick the missing stamp, and solve as many as you can before the clock runs out. Sounds easy? The patterns get sneaky: rotations, color cycles, mirrors, hidden rules, analogies... 11 different puzzle types keep your brain guessing. And Bob is watching. He WILL judge you. ◆ 35-SECOND ROUNDS Perfect for a coffee break, a commute, or "just one more try" at 2am. Every round is different. ◆ EARN BOB'S RANK Your score comes with a verdict — climb from "Lost in the Fog" all the way to "Master Postman." See exactly which puzzle types you ace and which ones fool you. ◆ A WORLD WITH CHARM A vintage 1930s post office, swing music on the gramophone, wax seals, and one very opinionated river otter. ◆ PREMIUM & PEACEFUL Pay once, play forever. No ads. No in-app purchases. No internet required. No data collected. Just you, the puzzles, and Bob. Think fast. Stamp faster. Bob is waiting.
