What is Three Walls about?
You are shown the shadow a shape casts on the front wall, on the side wall,
and from above. Your job is to build that shape, one block at a time, until
all three shadows line up at once.
There is a catch. Matching the shadows is only half of it — you must use
exactly the number of blocks shown. Fill in every square that appears in
all three shadows and the walls will match perfectly, and it will still be
wrong. Working out what to leave out is the puzzle.
30 stages, from a 3x3x3 space up to 5x5x5. Every stage remembers your best
solve, counted in moves, so you can come back and do it in fewer.
No timer. Take as long as you need.
