Congratulations! You found the Konami Code. The code was created by Kazuhisa Hashimoto who was developing the home port of the 1985 arcade game Gradius for the NES. Finding the game too difficult to play through during testing, he created a cheat code to give the player a full set of power-ups (normally attained gradually throughout the game).
Use this power-up to get $1.00 off mini golf now through 8/30/20. (Expired)
Use this power-up to get $.25 off waterice now through 10/1/20. (Expired)
Use this power-up to get $.75 off Par 3 golf now through 12/1/20
