About Fill The Bottle
Building a mental model of each container's internal boundaries is the core skill in Fill The Bottle. You must track which regions are already occupied and which paths remain open for incoming balls, constantly updating your map of the layout as you place each piece. The challenge lies not just in fitting the shapes, but in predicting how one placement will restrict your options for the rest of the bottle — a spatial reasoning exercise that rewards precise planning.
There’s something weirdly satisfying about fitting balls into oddly shaped canisters without letting them cross the line. Each level throws a new container design at you, forcing you to rethink your approach and plan your moves carefully. The puzzles start simple but quickly ramp up, keeping your brain busy. It’s one of those games where you keep telling yourself “just one more level.” Click or tap to play.
How to Play Fill The Bottle
- Click or tap to select a ball from the bottom tray.
- Click or tap an empty region in the bottle to place the ball.
- Fit all balls into the bottle without letting any ball cross the colored boundary lines.
- If a ball is placed incorrectly, undo or restart the level.
Game Features
- Each level presents a uniquely shaped container with interior partitions that restrict ball placement.
- Balls come in different colors, but color sorting is not required — placement is constrained only by shape and boundaries.
- A limited set of undo actions is available to correct misplacements.
- Progressive difficulty introduces containers with more compartments and tighter fit requirements.
- No timer or move counter — you can experiment freely until all balls are placed.
Tips & Strategies
- Study the bottle's internal lines before placing your first ball to identify dead-end compartments that must be filled early.
- Place larger balls first, as they have fewer possible positions and can block smaller balls if left for later.
- Use the undo button sparingly — plan each move by mentally simulating the remaining space.
- Look for symmetrical compartments and treat them as interchangeable to simplify your decision tree.
- If you get stuck, restart the level to refresh your mental map rather than forcing a jammed arrangement.
Frequently Asked Questions
What happens if I place a ball that crosses a boundary line?
The game will not allow the ball to be placed in a position that crosses a line. You must find a valid empty region that fully contains the ball's shape.
Is there a penalty for using undo?
No penalty — undo simply returns the last placed ball to the tray. However, the number of undos may be limited per level.
Can I rotate the bottle or the balls?
No rotation is possible. The bottle and balls are fixed in orientation; you can only place balls in the orientation shown.
Are all balls the same size?
Balls vary in size and shape (e.g., small circles, large ovals). You must fit each one into a region that exactly accommodates its dimensions.
