Filled Glass 3: Portals

Fill the glass to the line without spilling a single drop — portals will bounce your pour in ways you definitely didn't see coming.

Filled Glass 3: Portals is the kind of game that looks dead simple on the first level, then suddenly you're 40 attempts deep and muttering about trajectory physics. You're pouring a stream of little balls into a waiting glass, and there's a marked line you need to hit. Overshoot and you lose balls; undershoot and the level won't complete. The twist? The stream passes through portals that fling it in directions you never intended. I remember one level where a portal sat just above the glass rim, angled downward. I thought I could just dump everything through it and watch the balls drop neatly inside. Instead, they shot out the bottom portal, skimmed off the edge, and scattered across the table like dropped marbles. Took me six tries to realize I needed to open the valve only halfway and let the portal's curve do the work. The controls are simple — click or tap to start the flow, release to stop, or hold and adjust based on your platform. But the timing is brutal. Some levels have moving portals, or two portals linked in a chain that require a precise bank shot off a wall. I kept telling myself 'one more try' because the reset is instant and the satisfaction of hitting the fill line perfectly is weirdly strong. The physics feel slightly bouncy, which is fine once you learn to account for the little ricochets off the glass rim. There's no timer, so you can sit and plan, but you'll still mess up because the ball stream is continuous and unpredictable over long pours. Don't expect a story or any unlocks — this is pure arcade snack food. Perfect for a five-minute break that turns into twenty. The difficulty ramps up steadily, but never feels unfair; every failure is a lesson in portal geometry and valve discipline. If you like physics puzzlers that respect your time but mock your aim, this one's worth a shot.

Use mouse or touch the screen!

Aim for the portal's edge, not dead center — the rebound angle is tighter and way more predictable. Start with a half-open valve and watch the first few balls land before committing to full flow. When a level has moving portals, time your pour for the moment they swing into the sweet spot. On touch screens, use a long hold instead of tapping repeatedly; the stream stays steadier. If you're close to the fill line, ease off to a trickle — overshooting by a few balls still counts as a loss.
