Bomb
Don't be the one who hits it.
A bomb hides in the range. Take turns narrowing it down — solo or with up to 8 friends. Hit the bomb and it's game over for you.

Number Bomb
Corner the bomb without triggering it
Solo or Party. You Choose.
Play alone to beat your own record, or turn it into a party game with friends.
Shrinking Range
Each safe guess tightens the boundaries. Watch the range collapse as you close in on the bomb.
Multiplayer Relay

How to Play
Works in solo mode or as a multiplayer relay — the rules are the same.
Pick Range & Mode
Choose a range (1–50, 1–100, 1–1000, or custom). Toggle "Challenge Your Friends" for relay mode with 2–8 players.
Guess a Number
Pick a number in the current range. Safe? The range shrinks. In relay, pass the link or QR code to the next player.
Defuse or Boom
Corner the bomb to a single number to win. Hit the bomb and you're out — in relay, the other players celebrate!
Strategy Tips
Solo: Edge Play
Guess near the edge for safety, or the midpoint to narrow faster (but riskier).
Guess 5 → Safe → 6–100
Guess 95 → Safe → 6–94
... narrow until 1 number remains
Relay: Trap Your Opponent
Try to leave the next player a tiny range. The smaller the range when it's their turn, the more likely they'll hit the bomb.
P2 guesses 90 → Safe → 51–89
P1 guesses 52 → Safe → 53–89
... keep cornering each other!
Frequently Asked Questions
How does Number Bomb work?
A secret bomb number is hidden within your chosen range. Each guess narrows the range: if your guess is below the bomb the lower bound rises, if above the upper bound drops. Hit the bomb and it explodes — corner it down to one number to defuse it.
How does multiplayer relay work?
Toggle 'Challenge Your Friends' in the setup, pick 2–8 players, and create a challenge. Each player takes one guess per turn, then passes a link (or QR code) to the next player. The player who hits the bomb loses!
How do I share a challenge?
After creating a challenge, you get a QR code and a shareable link. Friends can scan the QR code or open the link to take their turn. After each guess, a new link/QR is generated for the next player.
What's the best strategy?
In solo, guess near the edges for safety or go bold with the midpoint to narrow faster. In multiplayer, try to leave your opponent a dangerously small range without hitting the bomb yourself.
What range should I pick?
Start with 1–50 to learn the mechanics, then move up to 1–100 or 1–1000. Larger ranges mean more rounds and more tension in multiplayer.
How is this different from Higher or Lower?
In Higher or Lower, you get directional clues and the goal is to find the number. In Number Bomb, the goal is to avoid the number — and in relay mode it becomes a competitive party game where each wrong guess means you lose.
