Prof. Layton: https://play.google.com/store/apps/details?id=com.Level5.LT1REU
Here is for IOS devices as well:
Monster Hunter Stories: $19.99
MHST The Adventure Begins: Free
I can barely play the one on Steam/console, but oh well!
How come? You mean spec/lag wise? Or difficulty? This is more akin to Pokemon than Monster Hunter 
Iāll edit the thread, wasnāt sure if it was available for IOS!
Download requires 4GB for what seems to be the demo. I already have just the essentials on my phone and still need to delete 2.3GB, so I guess I wonāt be playing Monster Hunter. 
Demo requires 1.3GB, the full version takes around 3.2GB or soā¦ (on Android)
Maybe heās on IOS, because there it requires 3.2GB for the demo and 4GB for the full version.
Well I was never a stickler for performance for games like this. If it runs at 30 fps Iām good, so it is mostly the difficulty that gets me. It beats the stuffing out of me all of the time. So I like the game but I find it frustrating enough to not want to play it. 
What @NICK9X9 said. Iām on iOS and it says that Monster Hunter Stories Adventure Begins (or whatever - the free one!) takes about 4GB according to the appstore page.
lol all this talk about 4gb reminds me of some years ago when i got a phone
chose the 8gb at the time, because it costed only a tiny bit more than the 4gb version and thought āwoo, double the spaceā 
then i get home and see the system etc ābasic functionsā took almost 4gb, and was like ādafuq, how is the exact same model with the same OS even freakin possible then with just half the storage?!?ā 
anyways, rando out of nowhere off topic thought process over, -carry on 
Donāt even get me started on the OS taking up most space. Every freakinā update makes me delete an music album or two. 
Maybe you should get a new phone or a SD card if thatās possible for you. I have 32GB internal + 64GB SD card sooo am cool wt my storage :3
Thatās one of Appleās many business schemes. Everything is fixed. You canāt change the battery and drive storage is fixed as well without SD slots, so youāre stuck with what you bought.
And I refuse to get a new phone until my current one, an iPhone 5S, literally breaks or becomes unusable otherwise. 
Right, I forgot thatā¦
anyway, if you donāt game and want to switch to Android, get the Moto G5, itās under 100ā¬ and has a sd slot AND replacable battery
Ok I did it, I bought it, I had to, itās good, I COLLECTED SO MUCH STUFF MWAHAHA
Does it have a headphone jack thou?
By the way, that aināt the only Prof. Layton game there, although those are spinoffs, not the main series, also, Iām just making my way through the entire DS games again, a shame Iāll never be able to get the downloadable puzzles despite they being on the goddam cartridge already dammit 
!!!
Yes indeed, itās basically a little budget āflagshipā in terms of physical features 
Ah well, Iām not too well versed in terms of the original Layton as Iāve never played any beforeā¦am just happy to see full price titles on mobile and it doesnāt look bad, does it?
Monster Hunter: Stories is super optimised for mobile btw, controls are exactly how one would expect them on a touchscreen, graphics are nice nice (could honestly be improved further but oh well) and there are all the things that make Nintendo games so great: attention to detail & quality gameplay
Which is why Iām kinda hyped for Layton as well
