How to play: there are 3 words that are jumbled in the tubes, related to the current category that is selected in the upper left. Tap a tube to pick up its top letter, then tap another tube to drop it. Build the 3 target words top-to-bottom in any three tubes. If any tube is correct, it'll highlight green to signify you have the correct word. Do this in as few moves as possible. Close this menu and play. Good luck!
