At the beginning simply use the white dices, you really don't care where you land at this point.
Once you start fully clearing squares, you'll probably want to use the red and blue dices alongside the white ones to make sure you evade empty squares, which you'll probably have a few if you have been farming, so you can still do it without buying them from the shop.
When most of the board is cleared, this is where you use the gold dices so you don't rely on RNG. The gold ones very rarely drop in some nodes, so this is where you'll probably have to hit the shop. You'll end up using most of them, so I recommend you wait for the better gold currency node to unlock tomorrow if you're at that point to optimize your AP usage.
