Verdict

The call

The clearest difference is rating: Brain Dots at 4.4 against Physics Drop's 3.6. Brain Dots also leads on ratings volume (8.2K vs 184) and update cadence (every 11 days vs monthly). Physics Drop's advantage is ads (none vs shown) and iOS requirement (8.1 vs 15.6). On price, in-app purchases, monetization model and device support there is nothing between them.
