Choosing the Correct Dice for Your Game
For most casual gamers, choosing gaming dice might be as simple as picking up a pack of six-sided dice at your local discount or mass-market chain. And if you only play HeroClix, this is correct--you only need 2 six-sided dice to play.
But what about all these other kinds of dice you see packaged in what look like "designer gaming dice" collections? Are they all really necessary for your gaming? Not at all, as the following chart will show you!
Common Types of Gaming Dice and Their Uses
 d4 Not used in M:TG, Clix, or SWMinis |  d6 Necessary for Clix Can be used for counters in M:TG and SWMinis |  d8 Can be used for counters in M:TG and SWMinis |
 d10 Great for M:TG life totals Can be used for counters in SWMinis |  d12 Can be used for counters in M:TG and SWMinis |
 d20 Necessary for SWMinis Great for M:TG life totals |
Generally, all dice are good for at least keeping track of counters, whether it's counters on a feat card in Clix, Force Points on a SWMinis figure card, or +1/+1 counters on a creature in Magic. d10s, d20s, and d6s are the most useful in the above games, but hang on to any others you've gotten--you might end up playing a game where you need them, too!
