There will be ways to access flash ...the only question is will WGT leave that version up and running for awhile post Dec 31st??
I expect they will JD, but I doubt they will be doing anything to it including updates of any kind.
One key question might be how synchronized are the flash and unity versions? For example, when WGT creates a Ready-Go tournament in the flash version does it automatically appear in the unity version or does it have to be created there too?
I could imagine it not just being a question of whether flash keeps getting updated (which it won't) or how increasingly buggy the flash game becomes (which it will) but also whether the new features and competitions that are rolled out in the unity version of the game are also accessible in the flash version in 2021.
I'm just speculating of course because we won't know until we get there, but it doesn't seem like wild speculation to me.
