Start with the tank targets
Look at the fish pictured beneath the open tanks at the top of the game. These are your current targets. Tap a fish of that type inside a bubble, and it moves into the matching tank. On a desktop, use the left mouse button. On a phone or tablet, tap with your finger.
The targets are not permanent tank colors. They change as you complete groups, so check the icons again after a tank clears. A fish that matched a moment ago may need to wait on your next move.
Three matching fish clear a tank
Collect three fish of the type requested by a tank. When the group is complete, that tank clears and receives a new target. Continue matching until you have collected the fish needed to finish the level.
Early levels include an introduction inside the game. Follow the highlighted fish and let the animations finish so you can see where each fish goes. The first level is a useful place to learn the difference between a bubble, a tank, and the holding tray.
Keep the holding tray from filling up
Fish that do not match an available tank go into the holding tray. In this version, the tray has five spaces. Filling the tray can end your attempt. Every unmatched selection uses space that you may need to reach a better fish later.
When a matching tank target appears, fish waiting in the tray can move into that tank automatically. This makes a nearly complete target especially useful: finishing it may open a target that clears some of your waiting fish.
- Check the tray before every unmatched selection.
- Prefer fish that can go straight into a current target.
- After a tank clears, look at the new target before tapping again.
Bubbles and obstacles
A bubble may hold several fish. Removing fish can empty a bubble and let other bubbles settle into reach. Later levels introduce obstacles such as frozen or locked bubbles. Pay attention to the instructions the game shows when a new mechanic appears.
A blocked fish is not the same as an ordinary unmatched fish. If it cannot be selected, inspect the obstacle and the available fish around it instead of repeatedly tapping the blocked spot.
Boosters and extra tanks
The game introduces Net, Clear, and Shuffle as you progress. You may also see an option to unlock an additional tank. Read the game’s prompt before confirming: depending on the action and your balance, it may use an item, coins, or an optional rewarded ad.
An extra tank provides another active target. It does not mean you can ignore the holding tray. Keep choosing matches and use boosters when they solve a specific problem. See the booster guide for more detail.
Play comfortably and keep your save
Use the fullscreen control above the game if you want more space. In the game itself, open the gear menu to adjust music and sound. On a small screen, portrait orientation usually keeps the tanks and tray easier to read.
