Mind wandering between tasks? Give it a challenge: spot a change, remember a sequence, or choose the ink color instead of reading the word. GAMES FOR A LITTLE DOWNTIME Play Sudoku or reveal 60 Nonogram pictures in the Games tab. These relaxing games are separate from training and do not affect your KTI or training statistics. New installations in regions with Premium receive 8 new games per day, shared across both games; continuing a saved game does not use a turn. Premium includes unlimited games. Previous free access is retained for people who trained before version 1.3.1; limits do not apply where Premium is unavailable. Game progress stays on this device and is not included in encrypted training backups. FIND YOUR NEXT CHALLENGE Race through Classic Schulte or alternate red numbers up and blue numbers down in Color relay, with grids from 3×3 to 6×6. Spot a moved or missing object in Change Detective. Visit every stop in Route Planning, recall everyday items in Shopping List, or rotate pieces to fill a shape in Rotation Assembly. Without Premium, the Today tab gives you a plan of three exercises a day, chosen for you, plus the daily challenge. Choosing any exercise yourself, playing as often as you like, and Shopping List and Rotation Assembly require Stillkeen Premium. Instructions and practice rounds help you get started. MAKE YOUR EFFORT VISIBLE See time, accuracy and rhythm where supported. Revisit sessions by date, compare results under matching conditions and collect badges for practice milestones. Follow changes in your KTI training index as you build your routine.
