Green Flag. Let us see if you remember both your history and flags. Easy Mode - Paint flags from around the world with randomly selected countries. Memory Mode - Test your memory and see if you can recreate the flag without seeing it.
Credits to @schmenry_ for the original project. Flag check part may be incorrect at times. I must warn you that some flags are borderline impossible. There are also a few flag repeats due to colonies having the same flag as their parent country.
