Balls — what Two Dots calls “nesting dots” — are little… well… balls that appear on the screen and take three hits to destroy. These hits can be from matches beside the balls, or they can come from bombs, gem blasts, cloud zaps, or erasers (it only takes one eraser to completely clear a ball). When a ball is cleared, it turns into a bomb, which can give you a nice chain reaction… or completely screw up your plans.
Balls don’t really require a strategy per se — they’re usually more helpful than hurtful. However, sometimes you’ll have balls ready to be cleared while you’re also trying to build a square, and in that case you should do a cost-benefit analysis. Will clearing the ball be better for you in the long run than making the square? You decide.
If this guide helped you out, please consider buying one of my stories from Amazon. Here’s one: Bring on the Rain, originally published in Asimov’s, is a post-apocalyptic tale of wanderers seeking water, and the war they must fight to survive. There’s a giant battle scene at the end, if you’re into that.
