SmartGames Tower Stacks

Most logic puzzles are flat. This one goes up.

Build a castle out of nine pieces. Lay the ground floor so the view from above matches the challenge, then stack everything that's left on top of it. The catch is that you're not told how many floors the finished castle has — you only find that out when it works.

80 challenges from easy to expert, and thinking in three dimensions is genuinely harder than it sounds if you've only ever done grid puzzles. Ages 8 and up, single player.

Perfect for: puzzlers ready to step up, spatial thinkers, and anyone who has run out of flat puzzles.
