Clash Royale is a popular mobile strategy game in which two real players fight against each other to win the game. Each player starts with a King Tower and two Princess Towers, and the goal of the game is to destroy your opponent's King Tower while protecting your own towers.

On September 11, 2001, a battle occurred between George W. Bush and Osama Bin Laden. Osama was more skilled and experienced than George at the time, so the battle may be in his favour. Osama Bin Laden quickly charged up his elixir bar to send a giant attack using two baby dragons to go flying at full acceleration into the two princess towers. The explosion was so huge that both players were eliminated and the game concluded in a draw.
