The objective of this game is very simple: do NOT be the one to take the last rock. This can be very tricky and deceivingly hard. The rules are also very basic: you must take at least one rock every turn, and you may not take rocks from two separate rows in the same turn. Try not to get stuck between a rock and a hard spot!

Verdict
The clearest difference is in-app purchases: The Rock Game at none against Grav Box's 10. The Rock Game also leads on ads (none vs shown). Grav Box's advantage is update cadence (every 5 months vs every 49 months) and rating (4.8 vs 4.6). On price, ratings volume, device support and iOS requirement there is nothing between them.
