4A

4A is a compact logic puzzle game where players try to deduce an opponent's secret digit number using simple but sharp feedback. Each guess returns two clues: A for digits correct and in the right position, and B for digits that are present but placed incorrectly, so every attempt narrows the possibilities. Players who enjoy deduction, pattern recognition and head-to-head challenges will find 4A satisfying: rounds are focused, rules are easy to learn, and a single perfect result of 4A means a win that rewards careful analysis and smart guessing.
