Overview
4 Square focuses on completing the 1–2–3–4 sequence multiple times by hitting targets and rollovers in order. Each completed sequence awards points and resets the progression, encouraging consistent, controlled play. As players advance, scoring values increase, adding a rewarding layer of progression.
Completing all sequences lights the “Special,” giving players the opportunity to earn replays. The layout is simple but skill-driven, making accuracy and shot planning essential.
