Climb from the 1st floor to the 11th by spelling a real English word on each of 10 floors, using the letters on the wheel. Tap letters to build your word, then submit. You can use each letter as often as you like, but you can't use the same word twice in a climb.
Words get longer as you climb: 5 letters on floors 1 to 3, 6 on floors 4 to 6, 7 on floors 7 and 8, 8 on floor 9 and 9 on floor 10. Every floor has its own time limit, shown by the bar.
A wrong word or running out of time drops you to Ground Floor. Then you try again.
The clock starts at your first floor and never stops, retries included.
Accuracy: a green 10/10 means you never gave a wrong word. If you did, the red number is the floor you first got wrong. Running out of time isn't a wrong word.
