I was heavily considering getting the Fire HD 10 and installing the Google Play Store on it. The price is just unparallel, there quite literally does not exist another tablet with this kind of hardware with this kind of price. The Fire HD 10 also has an IPS 1080p screen. 225 PPI. As long as I can run Google Play alongside Amazon's shitty software I'm happy.
It's incredibly hard to recommend a tablet, when you don't put a budget that you want to stay within without going over. But I've listed some stuff below that I personally thought was 'cheap' when google searching 'android gaming tablet 2019' and 'budget android gaming tablets'. I kept pricing under $300, hope that helps best of luck to you.
Dragon Touch K10 - $109 on Amazon right now, probably the cheapest tablet I've found again like most other Android tablets. I don't know how well it'll do for gaming. But you can search for reviews on YouTube about the device and come to a conclusion.
Fire HD 10 - $149.99 on Amazon, you can install the Google Play Store on it, if it's any good for running games that I don't know. But there are guides (you can google them) that tell you how to install the Google Play Store.
Lenovo Smart Tab M10 - $179.99 on Lenovo's website, again not sure how well it will do for gaming. But I'm sure if you search YouTube you will find reviews on the device, and can come to your own conclusion.
Samsung Galaxy Tab A 10.1 - $219 on Amazon, don't know much about this tablet if it's good for gaming or not. But you can search YouTube for it. I'm sure you will find a few reviews on it.
Apple iPad 6th Gen (Latest Model) - Amazon has it on sale for $249, regular price is $329.99. Great device (I own one it runs games buttery smooth), will last you years definitely worth getting I'd even recommend getting the 128GB Storage Model if it's in your price range.
