JJMXWillow is a vertical number deduction puzzle mobile game centered on "input guess—read feedback—narrow the range." Players use a number keypad to form a guess and submit it; the system responds with "higher" or "lower" and dynamically shrinks the remaining range on a candidate bar. A heat meter indicates proximity, and previous guesses are recorded as color blocks to help players quickly apply binary search strategies. The game starts with a classic mode and then alternates with variants such as timed blitz, parity hints, echo highlights, and extreme squeeze. The number range expands from 100 to 1,000 as levels increase. Correct guesses score points and build combos, while mistakes or timeouts cost a life; three lives lost end the round. Simple controls and tight pacing make it suitable for quick play, yet it tests strategy and on-the-spot judgment.
