Assuming I don't own a 3DS, what's the cheapest

by not playing them at all.

There are no working 3ds emulators so you'd have to buy a used old one

buying a used 2ds for ~$50 USD then proceed to place a CFW if the firmware can be downgraded. After getting the CFW, you should be able to download and play the games without paying for them.

Buy a cheap 3ds, or steal one from a child

70 dollar 2DS

I'd go for the 115 refurbished 3DS XL from Nintendo though
