For years I have been trying to solve the 3x3x3. Over the last several weeks I was determined to do it. With the help of several online tutorials and video's I can now solve it. My average is probably very slow compared to what you can do I am around 4 minute solve now. I am doing this on a normal off the shelf Rubik's cube its not a speed cube and is slow to turn and locks up from time to time when I try and go to fast.
My question may be a bit broad, or opinion based but I really need your help in deciding what I should do next. Should I go for a speed cube 3x3x3 and try and improve my times or should I try a 4x4x4? or both :)
Update in response to comment:
This is more for me, I have no intention of entering speed contests. It might be fun to be a little faster. I do think I need to memories the last 4 steps I still have to look at my cheat sheets to solve the last face on the 3x3x3.
Background I have been solving every wooden IQ puzzle I have found for the last 10 years. This is me moving to what I guess are called twisty puzzles. Back in the 80s I had and solved the pyramix, rubik's magic and the snake thing. I find sitting there and trying to figure them out a challenge and I enjoy sitting on the couch at night just messing with it.
I am fascinated by the concept of the megaminx but I think it's probably too soon to move to that.
In an attempt to be less broad, maybe I should ask what I should try next, that won't be too much too soon.
