I love mini games and the simpler they are, the better. For example, I recently got into a nostalgic mood playing minesweeper game. You can also try minesweeper play on https://www.1000mines.com . The cool thing about this game is that you don't even have to download it to your device, and you can just enjoy the game online. I can play this game for hours and I won't even get tired one bit.
