Happy Glass 3

Draw a single line to guide every last drop into the glass—sounds easy until the obstacles start moving.

Happy Glass 3 takes the draw-a-line puzzle hook and dials the fiendishness. You've got a glass (usually frowning) and a stream of water, and your only tool is one hand-drawn line that freezes into a solid ramp, dam, or shield. What's new here? Moving gears, swinging pendulums, fans that redirect water, and levels that make you think three steps ahead. The ink meter is your real enemy—run out mid-draw and the line stops dead, often ruining everything. I remember a stage with a spinning saw blade directly over the glass. Every time I drew a straight path, the saw chopped it and the water spilled. Then it clicked: draw a curved loop around the blade's arc, letting water hug the inside of the curve. The glass filled with three drops to spare. That eureka moment is what keeps me coming back—not every puzzle works, but when it does you feel like a physics wizard. Later levels punish impatience. Water has weight; if your line dips in the middle, it'll slide off. Use the least ink possible—a short wedge beats a long winding path. And if a fan is blowing left, don't fight it: tilt your line to channel the flow. You'll fail a lot, but reload is instant, so throw spaghetti at the wall until something sticks.

Touch or mouse

Use short lines when possible—less ink means more room for a second attempt after a mistake. Watch how water behaves on steep slopes; 45 degrees sends it flying, shallower angles drip. Draw around spikes and saws, never through them. Your line breaks on contact. In levels with fans, angle your line to redirect the airflow instead of blocking it. If your first line fails, undo instantly and redraw before the water starts—timing matters. Keep an eye on the ink meter; leave a tiny reserve for last-second adjustments.
