The right stack makes the whole night play
Hand every player a random fistful of chips and the game stalls — no one can make change, the blinds don't divide cleanly, and you're colouring-up by level three. A proper distribution gives everyone an identical, playable stack: plenty of small chips for the early blinds, a few big ones for later, and a total that matches the buy-in exactly. Set it once here and the night runs smoothly from the first hand.
