For example, the sentence "Items need sets equal colors min 3 to horizontal line".
"Items need sets" and then "equal colors". The first part is already a complete sentence, so it doesn't make sense for the second part to be there. Do you mean "Items need sets of equal colors"? Then what does "min 3 to horizontal line" mean? It doesn't make sense at all.
Then the next sentence: "Equal color blocks near by vertical and horizontal will clear". You have "Equal color blocks near ____ will clear", in the blank should be a noun phrase, and "by vertical and horizontal" is not a noun phrase.
