Yadoku

A daily dice-placement puzzle. You place dice one at a time on a small grid, and every row and column gets scored against a list of combos: Two Pair, Small Straight, All Odds, Four of a Kind. The same die counts toward both its row and its column, so each placement is a tiny optimization problem.

Same dice for everyone, every day. The same 16 random rolls land in your hands as in everyone else's. Your score sits next to a histogram of the world's scores on the same puzzle. Was today an easy 8/8 or a brutal 4/8? You'll know.
