Focus on 1 crab if you are F2p

I play on iPhone SE 2016 At first I was ready to uninstall the game because of how fast it drained my batteries but this was pretty much solved by changing graphics from mid to low. After you get past the quick tutorial of this game you get put into a battle against other players, what u don’t know is that this sort of easy noob arena where you can easily become king crab continues until you reach a certain rank, after that you suddenly find your self in the arena with the strong players and you will keep dying to what you would call Pay 2 win players. A lot of people say that the game is pay 2 win, yes there are consumable boosts like “faster growth” and “magnetic”. spenders would definitely have a lot of these. But The mega and legendary crabs and the upgrade points for the crabs are not pay 2 win, these are fairly easy to obtain as a F2p by simply playing the game and climbing the ranks / completing quests for gacha spins. Upgrade points are rotated in the shop. Here’s what I recommend, if u are going to be F2P you must focus all your attention on and main 1 crab. That 1 crab will gain levels as you play, each level represents 1% growth to your crab, so let’s say your crab is level 80, it will enter the game at 80% growth. All your earned pearls you would spend them on buying upgrade points from the shop rotation and soon you have your self a crab that easily competes with the pay 2 win.

Thank you for the very detailed review and 5 stars! We continue to balance the game and as you mentioned, introduced ranked servers so that similar skilled players will battle against with each other. All crabs have a strength and weakness, even the legendary crabs. Finding the crab that best fits your play style and levelling it up is good advice. Worth noting the more crabs you have levelled up, the more scavenger coins will be available to collect. We have plenty of updates planned for the future!

Great customer support, my favorite game

I have been playing this game for years, I absolutely love it. Unlike most games, there are NO ADS unless you want to watch them to get prizes & in my opinion this is by far the best way to get people to not hate ads. You have to work your way up but you can do it & you can make friends to help you along the way. I had a misunderstanding on my part (I thought it was on their part originally), so I emailed them not expecting much back bc most big app developers don’t care....well the next day I received a response from them. A very detailed response that made me realize the mistake was on my part but they were very kind about it. I was so appreciative of the response and the support I received, it just made me love this game even more. I have spent money on this game when they have deals bc I believe this game is very valuable, detailed, so well made, and the developers should be compensated for their hard work and dedication. I am amazed that this app is free but I am grateful bc I rarely pay for something on the App Store before I know if I will enjoy it or not. Thank you so much to the developers. This should definitely be the number one app/game.

Thank you for the review. We are not aware of an issue with incorrect ranking points being calculated but we shall investigate. What would be really useful if you could send us some screen shots before and after of your rank total when the bug occurs. Our support email being:

Alien crab ability is way too op

I recently got Robot Crab from crab grab (yay finally I get a crab that is mega rare or higher) and I’ve nearly maxed its hp with a little points in damage, in game I’m max growth and I attack an alien crab. It than proceeds to use its ability and kill me in seconds. What? That is so busted. I understand that it’s a legendary but Robot Crab has an average-pretty bad ability, why does alien crab get to have such a busted ability? (To be fair Robot crab is new so it’s ability will probably be buffed in some way, another thing I would like to see as it’s easy to avoid) This is not the only time, I’ve constantly been killed by alien crabs that use their ability’s and run off knowing that the little aliens do way to much damage and there is too much of them. I really like the way this game is going. And if alien crab gets an ability nerf it would fix an issue, also I notice not much people write about alien crab ability because they have bought it and they’re using it to kill way too much stuff so yeah. Btw if issues that most people are suggesting to be fixed/added back in (friendly mode I’m looking at you) than I’m positive that I will give a five star review as this game is really fun and worth the grind! (a while ago I got lobster from trophies reward, I took a break and I’m back)

Thank you maxx osorio for your descriptive review and 4 star rating. With all new updates and introduction of new content. It can be tricky to get the balancing right first time so we continually tweak and re-balance all crabs many months after their initial release. This would included the Alien crab's special and we are due to reduce it's attacking prowess. The Robot crab is very new and we love it's special although we may tweak it to inflict more damage or reduce it's vulnerability position once firing the rockets. The more constructive feedback we receive, the better guidance we have on the changes to be made. Best regards, The Robot Squid Team
