Win's Space Invaders accumulates score across all waves in a single session, each cleared wave's total is added to the running score rather than being treated as separate records.

Higher-value top-row aliens killed early in each wave stack with UFO bonus hits and powerup-multiplied kills to build the session maximum before survival ends.

Advancing into later high-speed waves is disproportionately rewarding because the inherent difficulty of those stages justifies the greater point-per-kill rate.

The score history stores multiple completed sessions, letting players compare multi-wave survival results against shorter sessions to assess risk-versus-reward across difficulty levels.

Space Invaders is offline; all wave scores are saved locally with no account or internet required.
