[Searching for online slots with specific features]

Hi everyone, i'm really into online slot gambling lately. I especially like three types of slot:

- the ones that with each spin the wild move a single place up/down or right/left, for example Frozen Inferno and Batman v Superman Dawn Of Justice ;

- the ones where you can set yourself and lock your wilds, in order to come up with your own strategy, examples are Wild Gambler and Mamma Mia;
- the ones where you need to collect gems/coins/gifts above each reel, and when you are able to collect once for every reel you unlock a bonus game/free spins.

These are the ones i found searching around online casino, does anyone know other slots with one of these three features? Thank you!
