One great logical flash game (by Microgames)
Check your 3D logic
I am stuck on level 16 (there are 30 levels)
Update 1: I solved all 30 levels π
Update 2: Since I was asked (both in comments and on email) how to pass level 16, I have played the game again and made a screenshot for you. If you want to solve it – don’t click the link. If you decided to cheat, or that it is not solveable, check my solution. So, here it is: solution for level 16 for 3D Logic
Update 3: solution for level 19 for 3D Logic
