NN555Drop

Play a focused game of gravity-based connect four wherever you are.

Drop pieces into a seven-column board, read the landing spaces, and connect four in a row horizontally, vertically, or diagonally. Each match is built around short turns, visible threats, and the satisfying choice between creating an attack and blocking one.

Choose your pace:

• Play a solo match against three local rule-based opponents. Beginner spots immediate wins, Standard also blocks immediate threats, and Advanced values the center while looking further ahead.
• Pass the device for a two-player local match.
• Work through 36 tactical practice positions covering wins in one, only-defense moves, and double threats.
• Review the final winning line, turn count, and move replay after every match.

The home screen keeps unfinished matches available to continue. Settings let you control drop confirmation, legal-column hints, piece symbols, motion, sound, and the light or dark theme. Symbols and textures help distinguish both sides without relying on color alone.

The game is designed for offline play. Match data, preferences, statistics, and practice progress stay on your device. There are no accounts, online matchmaking, chat, advertising, payments, or leaderboards.
