NN555Realm

NN555Realm is a quiet, offline board game about reading space and turning the tide.

Place a piece to enclose a continuous line of opposing pieces between your new piece and an existing one. Lines can run horizontally, vertically, or diagonally, and a single move can reverse pieces in several directions. Every move must reverse at least one piece, so each choice has a clear tactical cost.

Play a local two-player match on one device, or face a local rule-based opponent across three styles:

• Beginner values immediate captures.
• Steady looks for safer edge positions.
• Advanced weighs corners, mobility, and the final count.

The opponent is a local strategy, not a claim of intelligence or guaranteed victory. Legal moves, the latest move, current counts, and the number of reversed pieces remain visible during play. If a side has no move, the turn passes automatically. The game ends when both sides are stuck or the board is full.

Continue a saved solo game, undo the most recent solo round once, and review the completed move list with final counts. Practice focused positions built around claiming corners, limiting mobility, and leading late in the game. A guide explains the rules with clear examples.

Preferences include legal-move markers, assist markers, and a calm, high-contrast board designed to keep both piece faces readable. Games, settings, practice progress, and results stay on your device. No account, network connection, chat, advertising, payment, or leaderboard is required.
