Doroppuboru

Doroppuboru is a simple sphere-matching game in which you drop a sphere onto identical spheres below to combine them and create a different sphere. You can play on a mobile device or desktop, using touch, a mouse, or the keyboard. Understanding how to move and release a sphere makes it easier to line up matching pieces.

How to play Doroppuboru

Begin the game, then move the sphere horizontally and drop it toward matching spheres underneath. When identical spheres meet, they combine and transform into another sphere. The main task is to place each drop with care so matching pieces can come together.

Take a moment to check where the matching spheres are before releasing. A small adjustment to the left or right can help align a drop with the pieces you want to combine. If you are playing on a phone or tablet, use a light, deliberate tap; on a computer, make sure the pointer is positioned where you intend before clicking.

Getting started

Press Enter to begin, then use your preferred input method to move and drop spheres. If a move does not go as planned, focus on aligning the next sphere with an identical one. Doroppuboru’s central mechanic is straightforward: match identical spheres so they combine into a different sphere. With careful positioning and the controls above, you can get comfortable with the game on mobile or desktop.
