Test Tubes. Water Sort Controls - How to Play (Desktop & Mobile)

Test Tubes. Water Sort uses only pointer input. Every move is two clicks: pick a tube, then pick where it pours.

Desktop controls

Left click a tube to select it; it lifts slightly. Left click a second tube and the first one tilts over it and pours its top layer. If the pour is not allowed, the selection clears and nothing moves. Clicks must be made one at a time; quick double clicks were ignored in my session. I used no keyboard keys.

Mobile controls

I played on desktop with a mouse and did not test the game on a phone, so I cannot confirm how touch feels. The only input the game asked for was selecting one tube and then another, with no dragging or keys.

Tips

• Each level shows LV and the level number at the top center, a back arrow at top left, and a gear at top right.
• The curved arrow at the bottom reset the whole level for me, not just the last move.
• The light bulb hint button started with 5 uses and performed one correct pour per press.
• The bottom buttons dim during a pour, so wait for the animation before your next click.
