.... the computer selects a combination of four colored pegs in a row.
Use deductive reasoning to find the correct pattern in a maximum of 8 steps.

Playing Instructions:

Set the Start/End button to the "Start" position

Choose peg colors -select 2-6 colors by clicking on them. A white ring surounds "active" colors. Click start when ready to begin play.

Fill a single row at a time. Choose peg colors by clicking on an "active" color. Click on any position in a row to place a peg. When a row is filled with four colored pegs, the computer gives the result.

A small black pin means the color and position of a peg is correct.

A small white pin means the color of a peg is correct but the position isn't.

Continue to another row. Using your powers of reasoning, determine which colors and positions are correct until a whole row has only black pins as a result.
