Null Master: Number Puzzle

Every round gives you a number. Your job is to make it disappear.

Null Master is a calm number puzzle built on one simple loop: you hold a hand of numbered cards, and you play them to bring the target down - step by step - until it hits zero. Easy to understand in ten seconds. Much harder to do without wasting a card.

No timer. No falling blocks. No clock counting down while you think.

The pressure in Null Master comes from your hand, not from a stopwatch. Every card you play is a card you no longer have. Play the obvious one now and you may be one number short at the end. Hold it back and you may never get the chance to use it. That's the whole game.

HOW TO PLAY • You start with a target number and a hand of cards • Play a card to reduce the target • Land exactly on zero to clear the round • Get greedy, and you'll strand yourself one number away

WHY YOU'LL LIKE IT • Think as long as you want - nothing is timed • One clean rule, no tutorial wall • Difficulty comes from decisions, not from reflexes • Quiet, focused design - good for a coffee break or a long queue • [Play offline, anywhere] • [Made by one developer, not a studio]

If you like Sudoku, Countdown, solitaire or 2048 but you're tired of ads between every level, Null Master is built for the opposite feeling: sit down, think, hit zero.

Can you clear every board without leaving a single card behind?
