About this game

Numbers and letters can hide clever rules. Can you spot the pattern before you choose? It may look simple at first, but a good logic puzzle asks you to observe carefully, compare details and think one step further. This is a text-based four-choice deduction puzzle game with 40 stages to clear. Read each question, study the clues in the wording, then pick the answer that best fits the hidden rule. How to play: ・Read the question carefully ・Compare the four possible answers ・Choose the option you think is correct ・Check the explanation after answering Whether you get it right straight away or learn from a miss, each stage is a quick little workout for observation, reasoning and concentration. Perfect for short breaks, casual brain training, number puzzles, letter puzzles and anyone who enjoys a neat moment of insight. Use your logic and aim to clear all 40 stages! Button and touch controls are supported, so you can play in the style that suits you.
