Flask Fiesta is a free water sort puzzle you can play online in your browser, with no download needed. Help Dr. Ada sort her fizzy potions in a glowing lab: pour coloured layers between glass flasks until every flask holds a single colour.
Walk a 72-level journey through six lab chapters, from the Bubble Bench to the Starlight Dome, with three stars to chase on each level. Race the clock in Speed Lab, where each solved lab adds 12 seconds, or solve a new daily lab every day. Undo is free, hints show a good pour, and a retry adds an empty flask when you're stuck.
The calm colour-sorting makes it a relaxing brain teaser for all ages, and it plays on phones, tablets and computers. Flask Fiesta is an original game made by the GamesYap team. Like logic puzzles with a twist? Try Tile Twist.
Yes. Flask Fiesta is free to play in your web browser, with nothing to download or install. All 72 levels, Speed Lab and the daily lab are free. Coins only unlock lab themes, which change the look of the lab.

Yes. It runs in the browser on phones, tablets and computers. On a phone you tap a flask and then tap where to pour, or drag between flasks. On a computer you can click, drag, or use the keyboard.
Pour the top colour layer from one tube into another. A layer can only go onto the same colour or into an empty tube, and each tube has limited space. Keep pouring until every tube holds just one colour.
Use Undo to step back, which is always free, or tap Hint to see a good pour. If you are really stuck, a retry adds an empty flask, which makes the level much easier to sort. You can also restart and try a new plan.
Speed Lab is a timed mode in Flask Fiesta. You sort one lab after another against the clock, and each solved lab adds 12 seconds. It suits players who want a faster challenge after the calm journey levels.
