Every time you click on a positive number, that number is decremented by 1, and four neighbors are also decremented by 1.

Verdict
The clearest difference is ads: SixFour Chess at none against Zeroing's shown. SixFour Chess also leads on update cadence (every 2 months vs every 18 months). Zeroing's advantage is iOS requirement (13.0 vs 17.0). On price, in-app purchases and device support there is nothing between them.
