An offline bomb-maze game: what works without internet

Boome Slime is a bubble-maze game you play on your own device, alone or with computer-controlled teammates. You place water bubbles, step out of their lines and use the blasts to open a way through. The core game does not need a connection. A few optional extras do, and this page lists them plainly.

What you can play with no connection

• 15 story chapters and hundreds of handcrafted expedition stages. Moving, placing bubbles, chains, crates, power-ups and stars all run on the device.
• Matches against computer opponents: one-on-one duels, team battles, candy collection and crystal transport.
• Practice. A free area for trying movement and bubbles. It does not spend entry coins or your saved support items, and it does not advance stage progress.
• Your progress. Saved on the device. You don't need to create an account to play.

What needs a connection

• Watching an optional ad, for example to open a coin chest. If an ad is not ready, the button stays hidden; nothing else is blocked.
• In-app purchases through the App Store.
• Game Center leaderboards and achievements, if you are signed in.
• Sharing a result, which only happens when you tap Share.
• Sending in-app feedback, if it is available in your version.

When a connection is available, the app can also use it for things like loading settings and ads. The game privacy notice explains what data is involved.

Not online multiplayer

Matches in Boome Slime are you against the maze and computer-controlled opponents. There is no online player-versus-player mode, chat or matchmaking, so a weak signal on a train or a plane does not change how a stage plays.

Where you can get it today

The full iOS edition is in Apple's review and is not on the App Store yet. On Android, a separate 50-stage trial is open only to invited testers; it is not the full game. We will update this page when either changes.

Quick answers

Do I need Wi‑Fi to play?

No. Stages, practice and saving work without a connection.

Will I lose progress if I play offline?

Progress is saved on the device whether you are online or not.

Are there ads or purchases?

Yes, both are optional. Neither is needed to learn the controls or to use practice.
