Find your line among the stars. Four in a Row: Neon AI Battle is a neon strategy game from Hwanish Games. Drop a light into a column and connect four horizontally, vertically or diagonally before the AI. A GENTLER 50-STAGE JOURNEY Explore five cosmic sectors, with a boss every tenth stage. The AI now offers more openings throughout the campaign. Your completed stages and saved board carry forward. 100 TACTICAL CASE STAGES Solve prepared boards with winning moves, defensive blocks and forks. The original 30 puzzles are joined by 70 new cases. Unlock them in sequence, with progress saved separately from the campaign. Undo and Hint are unavailable in cases, including saved bonuses. Retry is immediate and free of ads. The top banner keeps its reserved place. FEWER INTERRUPTIONS Interstitial ads are less frequent, with a longer startup grace period and at least ten minutes after a full-screen ad before another interstitial can appear. Case retries have no ads. Unavailable ads never block progress. RETRY, HINT AND UNDO In the AI campaign, Retry starts a fresh board on the current stage; an occasional interstitial may appear. An optional rewarded ad provides a recommended-column hint or rewinds your last move and the AI reply, up to two ad undos per match. Saved Bonus Hints and Bonus Undos can be used without an ad. BIGGER BONUS RACE REWARDS Practice switching lanes, then survive 20 seconds to earn two Bonus Undos and two Bonus Hints. After a successful or failed race, an optional rewarded ad grants two more of each, once per race. A successful race plus that ad earns four of each. NEARBY VS Challenge another nearby iPhone using Google Nearby Connections over Bluetooth and local Wi-Fi. Create a room on one device and find it on the other. Verify the matching connection code on both devices and keep both apps open. Bluetooth and Local Network access are required. Undo, Hint and Retry are unavailable in VS. Both players must agree to a rematch. PLAY AT YOUR PACE Three original music tracks, sound controls and reduced motion. The campaign and cases work offline, with progress saved on your device.
