So smart!!!! I don't really understand the purpose of the dice landing on a reroll though as it doesn't contribute anything to the game and just forces you to roll again.
Other than that, design-wise this is my favourite one so far.
Ah cool! That makes total sense :). Would it have severely changed the game's balance if you repeated one of the other tiles twice?
Another thing you could have done is make it a "Extra Points" roll instead of just a reroll. That way it doesn't feel completely pointless as you'll get a few extra points for landing on there and then rerolling
