I can't open adobe flash player

As of the end of the year, nothing. If the developers don't release non-flash versions of those games, they will cease to function entirely.

Adobe announced in 2017 that Flash was being deprecated and that all support would end on 12/31/2020.

So how do I get to play some games? What do I use?

Ask the game developer what their plan is to have people play their games.

Flash is dead.

Most major browsers have already terminated support for, and the ability to run flash. Those that haven't will do so by the end of the year.
