Useful Tips for New Starters
After you died, please check your trophies in Rank. Collect your trophies.

Upgrade your crabs (skills, upgrades, etc.) on Edit (press on your crab).

The moment you see the big crabs, run away elsewhere. Don’t mess with them!
Try to attack by looking at the weapons of online users.

You can attack crabs that are not online, but try to attack them with weapons you get from boxes.
Looking at the map in the upper right corner, try to go where the boxes are, because guns, shields and health come out in these boxes.
Do not go to the regions where there are King Crap if you are not King!

Be careful crabs having this weapon:

Another huge tip is to make sure to play the game on mobile as well as your steam account on pc or console since the mobile app allows you to watch a ton of ads for extra lives, loot, skill points, crab pulls, mega magnets etc.
Last patch as a sad, sad day when they nerfed magnets to cost only pearls now.
