Ignition — Dropline Connect 4

Ignition - a classic four-in-a-row game against the AI. Take turns dropping discs and try to connect four before the computer does. Tap a column to place your disc. Build a line across, down or diagonally, while watching the board and blocking the AI from completing its own row. Every move changes the available lines, so a strong turn can set up your next attack or stop the computer just in time. Play against a genuine minimax AI with three difficulty levels. Choose Easy for a gentler match, step up to the middle setting to sharpen your tactics, or pick Hard for a tougher opponent. The computer searches possible moves using minimax with alpha-beta pruning, making each match a contest of planning rather than luck. Learn to spot open lines, defend key columns and think one move ahead as the board fills. Choose lines that open a move while limiting the computer's replies. • Three AI difficulties powered by minimax and alpha-beta pruning • Fully offline: no accounts and no network connection • Local best scores saved on your device • Instant restarts for quick matches • Clean, readable visuals • No forced ads and no pay-to-win mechanics An Ignition match is easy to start: choose a difficulty, tap a column and see whether you can outthink the AI. Play a quick match during a break, try another level after a close game, and keep working toward a better local score. The rules are simple to learn, but every board offers new choices about when to attack and when to defend.
