Best Multiplayer Backend Tools in 2026

Kabza is a real-time multiplayer strategy game where players compete to capture and hold wards on a map. Each player starts with a set of wards that grow supporters over time. To capture an opponent's ward, you drag from one of your wards to send half its supporters as a rally. When the rally arrives, it fights the defenders one-for-one; if you have more supporters, you take the ward. The game supports up to 8 players on separate phones, with empty seats filled by bots. Players can form temporary alliances (coalitions) to reinforce each other, but alliances are private and last 90 seconds. The goal is to hold three-quarters of the wards to win by landslide, or after 10 minutes the player with the most wards wins. Kabza offers adjustable settings including number of parties, map size, bot difficulty, rally speed, and a sudden death mode that accelerates growth after three minutes without a capture. The game is free to play and works in a web browser, with full-screen support on iPhone by adding it to the Home Screen.
