Hi bluebe123, thanks for the feedback! The number on the bottom of the dice doesn't matter so much as the number on top. Our intent with the second puzzle was for it to teach the key mechanics: you must match the number with a blue-dot tile, and avoid the number with a red-dot tile. We might have to have another go at that sometime to make it more effective as a tutorial.
A useful thing about dice is that opposite faces add up to 7, so you can use that to always know what's on the bottom of the die if you need to. We could probably find a way to teach that in the game too.
