Easily the best game around at the moment. Very clear and smooth graphics. So many different types of games within one game. Lots of freebies each day too. Be warned, you may just spend money on this for offers and perks. I very, very rarely spend money on games, but I've let myself down on this one! No ads either, unless you want a freebie. Download it and suddenly realise you've spent hours playing it when you should be working 🤫

While I'm enjoying this game far too much, the cost of most things are stupidly high. Does any moron really pay £25, £50,£100 for some of them? I don't mind paying 99p or the odd £5 every so often, but that's it. Lastly, there's a glitch that's not giving me a repair base option once I've upgraded all my ship options each game, only the coins, please fix it. Ty. EDIT 7-Aug-26 Still getting the issue, sometimes first coin I get the apple too, but not on the 2nd.

Hello! Thanks for the review and high rating. We hear you on pricing and will keep balancing offers. Sorry about the repair-base glitch (first coin sometimes gives the apple, not the second). Please email support@gamegears.online with your device, OS, game version, and steps so we can fix it. Thanks!

Good fun to play. You don't have to pay for things to progress but it does seem you need to pay (when I tested this it was about £20 in packs) in order to win the best weapons in events. That is a bit sad as it is out of reach for the most part for people like myself. The base game gives good rewards though and is enjoyable.
