i can only play super mechs round my nans house because my computer is broken so all i have is a tablet and super mechs is not on the play store so i can only play on the weekend.So plz put it on there somehow.

Yes, Supermechs is not on the Play store or the windows store.
only 4 options.
1. Fix Your Computer.
2. Get a apple device that supports supermechs.
3. borrow a computer or borrow a apple device.
4. Or you can listen to me, And i can tell you how to play it on your android phone.

Anyways, it can be buggy.. But it does work, Since supermechs needs Java Flash player to run.
browsers on normal android phones do not support it.
But!! There are actually some browsers that you can download from the play store that support flash. The one i used was "Puffin Browser" Im pretty sure, I dunno. Try typing that in then "Puffin" or something.
It has a picture of a bird xD
Now it did work for me, But if it dosnt look up on google and find android browser that supports Java/Flash or whatever. You will find one, Honestly, I have played SM On my Android phone, PS Vita, Ps3 (Haven't tried ps4 or Xbox one) i done it on my wii and i then got an Iphone :p
So its possible, Probably not the answer you were wanting, But you can actually play SM on your android phone as well as other games (:
