The Binding of Isaac: Rebirth

I've encountered some interesting new "Dice" rooms, which have a large dice pattern on the floor, with the number of dots being randomised. Stepping onto the pattern will do something different depending on what number is on the dice.

So far i've noticed:

 Spoiler

2 - randomizes all pick ups in the room/on the map, not too sure. like the D6 item I think it was?
5 - Resets the level and re-rolls the layout, starting you at the beginning again (but you keep your items)
6 - Completely randomizes all of your items, getting rid of all the ones you have picked up and replacing them with new ones from the item pool. Absolutely crazy. It completely changed my game once I found this. I got a crap ton of items too, more than I had originally i think.
