Bomb Bluff
Read full descriptionHide full description
**Bomb Bluff is the ultimate 2-player battle of wits!** One player secretly hides a bomb on a number. The other player must read their opponent, choose a number, and try to avoid the bomb. Bluff. Guess. Take risks. Outsmart your opponent. With just one iPhone, two players can enjoy an intense psychological battle that's simple to learn but surprisingly exciting. ### How to Play * One player secretly places a bomb on one of the available numbers. * Pass the phone to the other player without revealing where the bomb is. * The other player chooses a number and tries to avoid the bomb. * If the number is safe, you earn points equal to the number you chose. * A successfully chosen number becomes unavailable for the rest of the game. * If you hit the bomb, your score resets to 0. * Players switch roles and continue the battle. * Reach 40 points to win instantly. * Hit the bomb 3 times and you lose. * If only one number remains, the game ends and the player with the higher score wins. Every choice becomes a mind game. Did your opponent hide the bomb on a high-value number? Are they expecting you to play it safe? Or are they bluffing because they know exactly what you're thinking? The more you play, the more you'll start trying to read each other's habits and strategies. ### Perfect for Two Players Bomb Bluff is made for two people to enjoy together. Play with friends, couples, family, or anyone who loves bluffing, guessing, and psychological games. No complicated setup is required. Just open the app, pass the phone back and forth, and start the battle. ### Want a Quick Game? For a short and exciting match, we recommend: **4 Rounds + 8 Numbers** It's a great balance for a quick game when you only have a few minutes. Want a longer battle? Increase the number of rounds and numbers and enjoy an even deeper psychological showdown. Can you read your opponent, avoid the bomb, and become the ultimate Bomb Bluff champion?
