The player must enter a true addition sentence (i.e., the three-digit number to the right of the equal sign must equal the sum of the two-digit numbers to the left of the equal sign). Once an addition sentence is entered, the box around each digit will change to a color. The color key is provided below:[br][br][list][*][color=#999999][b]Gray[/b][/color][color=#444444]: [/color]The digit does not exist within the addition sentence.[/*][*][color=#bf9000][b]Yellow[/b]: [/color]The digit does exist within the addition sentence but is misplaced.[/*][*][color=#38761d][b]Green[/b]: [/color]The digit is an exact match.[/*][/list][br]The color of each digit can then be analyzed to discover a more accurate solution. The puzzle is complete once each digit turns green, showing that every digit is an exact match.[br][br]To demonstrate the rules, a video is provided below!

[list][*]How many different puzzles exist?[/*][*]If the third-place value of the sum is not 1, what information does this tell us?[/*][*]Given the color-coded addition sentence[b] [color=#bf9000]55[/color][color=#38761d] [/color]+[color=#38761d] [/color][color=#bf9000]30[/color][color=#38761d] [/color]= [color=#38761d]085[/color][/b], what are the only remaining possible solutions? Why?[/*][/list]
