Cups - Water Sort Puzzle is a casual sorting game similar to ball-sorting games but with a slight twist. A player must sort liquids of different colors into bottles and other containers instead of balls across nearly 400 levels. When they succeed with filling a container, the game pops a burst of confetti, seals the container with a cork automatically and turns the water into a fizzy beverage.
The different colors of liquid float on top of each other in a container without mixing together. The player sorts the liquid by pouring a specific color of liquid into an empty container or into a container that has the same color floating at the top. The player unlocks new levels with each success, but the game challenges them by increasing the number of liquids and containers to sort into beverages. The game provides the player with a handful of undo moves to make it easier to win.
The player earns coins over time that they use to unlock random containers in the game's Shop. They can increase the amount that they earn by watching an advertisement to receive a reward coin multiplier on a multi-colored spin wheel.
