Brilliant

From BoardGameGeek:

Grab the dazzling diamonds before someone else does! In Brilliant, you have to fill the fields on your sheet with numbers faster than everyone else. To do this, write one of the two numbers rolled next to a number you've previously entered. The grid is divided into areas of different colors for which different rules apply for entering numbers. The faster you complete an area, the more points you'll earn. The player with the most points at the end of the game wins.
