How to play
Aim: crack the hidden code within ten attempts. Easy uses four unique colors, Classic uses four colors that may repeat, and Expert uses five colors that may repeat.
Build a guess from the six-color palette, then submit it. A black feedback peg means one color is correct and in the correct position. A white peg means one color is correct but in a different position.
Feedback pegs do not correspond to individual guess positions.
