A RACE-THE-CLOCK NUMBER PUZZLE FOR iOS
Till Zer0
Every board gives you a target and a clock. Subtract tiles to burn the target down to exactly zero — overshoot, and you start the round over. Special tiles bend the rules; the clock never does.
SOLVING…
HOW IT PLAYS
Three rules. One clock.
Read the target
Each round deals a fresh board of numbered tiles and one target value sitting above it.
Subtract your way down
Tap tiles to subtract them from the target. Every pick counts — there are no takebacks and no pauses.
Land on exactly zero
Hit zero on the nose before the clock empties. Clean clears keep your streak — and your time — alive.
SPECIAL TILES
The tiles change the rules
FREEZE
Stops the clock cold for a few precious seconds.
BOMB
Armed with its own countdown. Spend it in time, or eat the penalty.
POISON
Pays out extra — then your clock drains faster while it lingers.
CHAIN
Starts a timed chain — keep clearing to keep the bonus rolling.
LOCKED
Sealed shut until you've cleared enough tiles this round.
RANDOM
A hidden value. You find out what it's worth the moment you commit.
SKIP
Wipes whatever's left of the target. Instant round clear.
SWAP
Re-rolls the tiles around it into new values. New board, same clock.
SHUFFLE
Reshuffles the entire board — and tips you points and time for the trouble.
DECAY
Its value rots away on a timer. Grab it early or grab it cheap.
NEGATIVE
Pushes the target back up — and pays you back in points and time.
LINKED
One of a pair. Clear it with its twin for the multiplier — break the set and the bonus is gone.
DIFFICULTY
Pick your pace
Roomier clocks and kinder boards. Learn the tiles without the panic.
The intended game. Every special tile in play, every second earned.
Lean clocks, mean boards. For chasing the top of the leaderboard.
