## What is Till Zero?

Subtract to exactly zero — before the clock runs out.

Every round gives you a target number inside a ticking timer ring and a board of numbered tiles. Tap tiles to subtract their values from the target. Hit exactly zero to clear the round, earn bonus time, and face a fresh board with a tougher target. Overshoot, and the round resets while the clock keeps draining. Time never stops — when it reaches zero, the run is over.

Easy to learn in one round. Hard to put down after fifty.

SPECIAL TILES BEND THE RULES
Twelve special tiles change the math when you least expect it:

• TIME FREEZE — stops the clock cold for a few precious seconds
• BOMB — comes with a lit fuse; spend it in time or take the penalty
• POISON — pays bonus points, then drains your clock while the toxin lasts
• CHAIN — your next move must be an adjacent tile, so think fast
• LINKED — comes in pairs; tap one and you're committed to its partner
• LOCKED — sealed shut until you've cleared enough tiles this round
• NEGATIVE — pushes the target back up instead of down
• RANDOM — a hidden value revealed only when you tap it, with a points bonus
• DECAY — its value rots away on a timer; grab it early or grab it cheap
• SWAP — re-rolls the tiles around it into brand-new values
• SHUFFLE — reshuffles the board when you need a way out
• SKIP — wipes whatever's left of the target for an instant clear

THREE BOARDS, ONE CLOCK
• EASY — a 3×3 board with gentle targets and a forgiving timer
• MEDIUM — a 4×4 board with bigger numbers and tighter margins
• HARD — a 5×5 board where every tap and every second counts
