You'll need to install Dolphin browser, as SpookDroid said. You'll also need to go into settings>security and enable "Unknown Sources"
Then you'll need to google search for a Flash .apk file, which will install Flash on your phone.
You should know, though, that the flash games you enjoy on your desktop or laptop will *not* be the same as what you get on mobile, and some games may not work at all, but some will. You'll need to use Dolphin, though, not Chrome.
