Full Cup

Full Cup is a drawing puzzle with a simple goal: fill the cup. Each level shows a source dispensing colored liquid and an empty container somewhere on the screen. You draw with your finger — lines, ramps, scoops, walls — and physics handles routing the liquid into the cup. The catch: liquid has volume, splashes, and pools, so a poorly-designed funnel can lose half your fluid before it reaches the goal.

Touch and drag to draw lines anywhere on the screen. Lines act as solid barriers that liquid flows along. You can draw curves, loops, walls, anything — but you have a limited ink budget per level. To start the flow, tap the play button. The cup must reach a "full enough" mark to clear the level. Restart anytime to redraw.

Funnels work better than ramps. A V-shape channel keeps liquid from spilling sideways. If you're losing volume, look for places where the liquid is splashing out — adding tiny walls there saves significant fluid. Don't draw too much; complex contraptions often perform worse than simple ones because liquid can get stuck or splash unpredictably. When stuck, try a totally different approach instead of refining the same broken design.

Full Cup rewards experimentation. Every level has dozens of valid solutions, and finding your own elegant design feels more satisfying than following a tutorial. The liquid physics are tuned to be unpredictable enough to be fun but consistent enough to be solvable. Watching your cup fill up — drop by drop — has an unusual zen quality.

For fans of physics-drawing puzzles. If you enjoyed Where's My Water, Crayon Physics, or any "draw to solve" game, you'll feel right at home here.
