Cannot into block building? This trainer will help you (I hope).

Select level (the more is the level, the more moves you need to build 2x2x2 block), it will give you the scramble. Try to solve it optimally. Press "Solve" and it will give you the right answer.

Fantastic! I get stuck in level 4, but I'm not even in my final shape. Sebastianos idea would be nice, hope to see it realized soon!

That means that, for example, among all states that can be solved in 4 moves 5640 states have only one optimal algorithm, 1119 have two optimal algorithms, 260 have three and so on.

Update:

Added another task. You have already built 2x2x2 block and want to expand it to 2x2x3 block.

PS: While every 2x2x2 block can be built in 8 moves, there is one possible situation of 2x2x3 block that can be built in 9 moves, it is with 2 flipped edges: U F2 D2 R D2 F2 U' D' B. I didn't include 9 level for this task because of consistency with the first task.

I may not be 100% unbiased, but I think a 3D cube view using RoofPig would be a lot easier to visualize.

It should also be very easy to set up, at least with help from the RoofPig author.

Apologies for the necro, but I just discovered this thanks to a youtube video and some other comments here on the forums.
This is very useful for training, especially when combined with a full solver such as http://laire.fi/jarcs/
Thanks for creating it!
