The ultimate challenge! Put your true skill to the test, and at a very high level, dodge the underwater mines that the submarine's sonar detects, the more underwater mines you dodge the higher your score. Let's go! I invite you, don't wait any longer ;)

Verdict
The clearest difference is in-app purchases: Blue Crystal Ball at none against Abyss's 2. Blue Crystal Ball also leads on iOS requirement (12.0 vs 15.2). Abyss's advantage is ads (none vs shown) and update cadence (every 10 months vs every 72 months). On price and device support there is nothing between them.
