The smaller parts (the 6 I cut above) if your dice land there is a 4x multiplier. the next tier up is a X3, next teir is x2 and the top teir is x1 (near the lip to teir 2) or x0 (near the initial roll area).
But score is not done until all dies are rolled for everyone. so you can (like the game bowls) roll your die to knock some one else off the board, and/or knock your own die to a higher scoring tier. but beware, you could knock some one else to a higher tier as well.
The die sets (same color for each player) I got are a D4, D6, D8, D10, D12 and D20. players can choose which to roll/when. I have 10 sets of different colored die, so the board (if 10 people are playing) should get really crowded.
The one rule for rolling die is that it must touch the rolling platform atleast once. so you can roll to it (like ping pong) or put the die there and flick it (like, soccer penality goal??)
This type of game is classed as a dexterity game.
