Mastermind is a game I play at school at maths extension. It is basically bulls and cows with 4 digits, and optional repeats. Hotkeys: Space to enter new input X to delete one Green flag to delete all 0,1,2,3,4 keys to set the right place numbers (bulls) to 0,1,2,3, and 4, respectively. P, Q, W, E, R keys to set the wrong place numbers (cows) to 0,1,2,3, and 4, respectively. Up and down to change right place numbers. Left and right to change wrong place numbers. A to toggle allow repeated digits. Turbowarp is highly recommended: https://turbowarp.org/763673221
Please ignore this if you don't understand any of this. This is mainly directed at @kapiti798 and @My_Name-Is_Jeff-, who go to the same maths extension class as me.
