Click on the selctors on the selctors to pick a color. Click until you get the color you want (the colors are displayed at the bottem left). You click on the selctors corresponding to the current level. (level 1 = selectors on bottom row, level 3 = selectors on the third row from the bottom). Click submit when you have chosen the colors you want. A red line means that there are one color that is right, but in the wrong place. Two red lines means that there are two colors that are right, but in the wrong place. etc. A white line means that there are one color right, in the right place. Two white lines means that there are two colors right, in the right place. etc. If you add the red and the white lines, 4 is the highest possible number you can get. Example: 2 red and 1 white line, means that three of the colors are right, two of them in the wrong place and one of them in the right place. The colors on the left are just there so you can see how many colors there are. They don't do anything, so don't bother clicking them. You have a total of 16 tries. Click submit only if all the selectors on the current row you are on have a color. 4 white lines and you win! If you get it right, you will get a message that says you have done it. It is possible that the answer will contain two or more of the same color, keep that in mind.
I made this game by myself, but it is a copy of the board game "Mastermind". Thanks a lot for 250 views!! My most viewed game by far:)
