Frequently asked questions
How do I play?
BombaDuel is a 1v1 minesweeper flags duel. You and your opponent share the same board. On your turn, tap a cell:
- If it's a safe cell, it reveals and the turn passes to your opponent.
- If it's a mine, you claim it (+1 score) and play again.
First to claim more than half the mines wins. If you fall 3 mines behind, a catch-up bomb unlocks that blasts a 3x3 area on your next turn.
What are the three board sizes?
You can pick the board before each match:
- Classic — 12×18, 51 mines (~5 minute duel)
- Large — 14×22, 76 mines (~8 minutes)
- Huge — 20×28, 140 mines (~15 minutes)
Pinch to zoom on the board if cells feel tight on larger sizes.
How does matchmaking work?
Tap Find Match from home. You enter the queue for the size you picked. The finder also shows how many players are waiting on each board size — tap a different chip to switch queues.
Pick Any size to pair with the first opponent regardless of board. If no one shows up in 18 seconds, the finder offers a bot match instead.
How do I sign in?
You can play BombaDuel as a guest against the bot, or sign in with email + password to play ranked matches online, save your stats, and appear on the leaderboard.
Guest play is limited to bot games. Random matchmaking and leaderboard require a signed-in account.
I got disconnected during a match. What happens?
If you leave or lose connection, your matchmaking entry is cleared automatically. Ongoing matches do not auto-resume — start a new one from home.
Bot games can be restarted from the end-of-game screen.
How is the leaderboard calculated?
Every online win, loss, or draw updates your ELO rating (K-factor 24, starting at 1080). The leaderboard shows the top 100 players by rating.
Bot games and matches you play as a guest do not affect the leaderboard.
Will I see ads?
This release does not show ads. If a future version enables ads through Google AdMob, you will be able to disable them in Settings. On iOS you will be asked once for tracking permission (App Tracking Transparency); your choice controls whether ads are personalized.
How do I delete my account?
From inside the app: open Settings → Account → Delete account. This removes your profile, ELO rating, leaderboard entry, and match history from our servers.
Account deletion is permanent and cannot be undone. If you prefer, email support@iocodo.com from your account email and we will process it within 30 days.
How do refunds work?
BombaDuel is a free download. If a future version introduces paid features, refunds are handled by the store you purchased through:
