oh also the game has adaptive difficulty so it won't get chaotic unless you ignite a lot of dice. the best thing to do is make a group of 6 6's and then keep adding to them before they explode
Interesting, and I captured another screenshot where it doesn't work:
since there are four dots on them, you need to have four touching in order to ignite them. hope that helps!
Alright I get it, so I was playing wrong. Thanks.
