This is a number puzzle game for iPhone that combines pattern observation, mental arithmetic, and rule-based judgment into a lightweight gameplay experience. You can choose from four modes: see how numbers cycle to the left and answer the number of shifts; reverse the absolute values and then flip the signs; keep only the digits that appear exactly once from a string of numbers; or determine if there is a pair of prohibited adjacent numbers. After selecting the difficulty, you enter a timed challenge. Correct answers earn points and extend combos. The answer is revealed when the time runs out for review. Daily check-ins earn points, which can be redeemed in the shop for items such as hints, skipping the current question, extra time, and "double score on the next question." Your profile page summarizes your total score, correct rounds, current combos, and best combos for each mode, and you can view your item inventory. The bottom Home, Shop, and Profile sections and the clean card-style interface make it perfect for playing a few levels in short bursts of free time, exercising your brain in a relaxed pace.
