>>8211831The only way is to get an old iPhone running an old version of iOS (10.3 or lower). Downgrading is generally not possible aside from some very specific examples so you'll need to buy it on that firmware.
10.3 is when Apple cut off support for 32 bit apps, and that TF game was sadly never updated for 64. I wish I could still play it, I miss it sometimes. It was like a TF version of Advance Wars.
