Make the glass happy

Draw a line, watch water bend around it, and suddenly that grumpy little glass is grinning. That's the whole trick behind Make the glass happy - no timers, no lives, just water that goes where you tell it to go.

This one's for the tinkerer, the person who'd rather sketch a wonky ramp and see if it works than follow a script. Each level hands you an empty glass and a puddle of water somewhere on screen, and your job is to figure out the shape that connects the two. Sometimes the answer is obvious. Sometimes you'll redraw the same line four times before it clicks.

Controls are as simple as the idea: press the left mouse button and draw on desktop, or tap the screen on mobile. It plays straight in the browser on Android, iOS, or desktop, no download required, so you can jump in between other rounds of Puzzle games whenever the mood strikes.

If you like puzzles that reward a bit of lateral thinking, this sits nicely alongside other Brain Training Games on the site - quieter, slower, but just as sneaky about hooking you.

Guide the water into the glass by drawing lines that redirect its flow - fill the glass and it's happy, level solved.

On a computer, hold the left mouse button and draw the shape you need. On a phone or tablet, just tap and draw directly on the screen. There's no other input to learn.

Start simple: draw short, deliberate strokes rather than one long messy line. A cleaner shape gives the water a clearer path, and you'll spend less time undoing guesses.
