2048 Balls is a numbers-merge game that combines elements from classic 2048 and bubble-shooter games. Instead of a player merging numbered tiles, they must merge numbered, ball-like bubbles.
The game takes place on a medium-gray field on a dark gray background. A green, dashed line runs horizontally near the top of the field. A single bubble with a number in it rests on the line. The player must drop the bubble to the bottom of the field and then continue dropping bubbles to merge bubbles of the same value to create new ones with higher values. For example, if they drop two red 2 bubbles, they make a yellow 4 bubble. An additional 4 bubble dropped on top of the first 4 bubble creates a green 8 bubble. Two green 8 bubbles create a blue 16 bubble.
The game supplies a dotted targeting line to guarantee a perfectly aligned drop. Also, the player can use the current bubble at the top of the field to push together two bubbles at the bottom because the bubbles aren't stationary. Instead, they float. As a result, the impact from a dropped bubble can make other bubbles drift into each other and merge together.
In 2048 Balls, the player can reset the field by selecting a double arrow button at the top left corner. The game displays their current and best scores at the top right corner.
