#8: This is a multi-level rolling block maze with the following rules:
1. Each of the dark blocks (A, B, and C) can roll in any one of four directions, using one of its base edges as the axis of rotation. The light colored walls are barriers, not blocks, and do not move.
2. A block cannot roll if it is obstructed by other blocks or barriers, if it would fall outside the edge of the maze, or if the new base would not be fully supported from below.
3. The blocks can never change levels. Block A must always rest on the floor of the maze, block B must always rest on the first level, and block C must always rest on the second level.
For example, block B and C cannot move first. Block A can only roll South. After that, block B could roll East, partially supported by block A. If instead block A rolled South twice, block C could roll West, supported by block A. The goal of the maze is to move block C on top of space X.
#9: Roll the dark cube from Start (S) to Finish (F) without the orange face ever facing down. The dark cube must stay within the boundaries of the 7×7 grid. The 10 light cubes are barriers that do not move.
#10: Each of the red blocks can roll, but never change levels. The gray walls are barriers which do not move. A block cannot roll if it is obstructed by other blocks or barriers, if it would fall outside the edge of the maze, or if it would not be fully supported from below. The goal is to get the top block to the Finish (F).
11: Rearrange the six vertical strips so that each row contains a true equation. Strips can be permuted and rotated.
