How to play
Choose an activity from the games menu, or follow the adventure journey through all eight activities. Each activity has five levels with five puzzles per level. Solving a puzzle moves you to the next one automatically. Completing a level brings up a celebration; in the adventure journey, finishing an activity returns you to the journey map.
In Sudoku, fill the empty squares so each picture appears once in every row and column. Select an empty square and then a picture, or drag a picture into place. In What's Next, study the repeating pictures or changing sizes and directions, then click, tap or drag the answer into the final slot. In Odd One Out, select the one picture that does not belong with the other five.
In Memory, turn over two cards at a time and find every matching pair. Matches stay face up, while unmatched cards turn back over. In Colour Logic, choose a colour and tap a region, or drag a colour onto it. Colour every region so neighbouring regions have different colours, then press Check. You can change colours or clear the board before checking again.
In Mazes, guide Leo to the goal with the keyboard arrow keys or the on-screen arrow buttons. If a key appears, collect it before reaching the goal. In Which Piece Fits, choose the picture that matches the missing silhouette, which may be rotated. In Logic Domino, study the dot patterns on the visible tiles and select the tile that completes the sequence.
Use the circular-arrow button to restart the current puzzle, or the back arrow to return to the games menu. Open Settings to choose English or Español and adjust the sound. Completed puzzles and stars are saved in your browser. For levels 1–4, finishing with no recorded mistakes earns three stars, one or two mistakes earns two, and more earns one; the final level awards three stars.
