Why Lackin

Built deeper for live Senior Assassin

Senior Assassin has real gameplay systems

Lackin is not just a map with eliminations. The app already supports Senior Assassin abilities, ability drops, bounty mechanics, blocked hours, and live alerts that make active games feel more strategic and dynamic while they are happening.

Relative location and zone logic are core features

Lackin supports relative location, zone entry and exit alerts, and richer map control for groups that want gameplay without always exposing an exact pin. It is designed for live play that balances visibility, tension, and privacy.

Dynamic zones keep the map from getting stale

Lackin Pro already includes moving and shrinking zones, multiple shared zones per group, custom zone colors, and dynamic map tooling built for live Senior Assassin pacing instead of static one-size-fits-all map rules.

Convex is at the core of the live product

Lackin's core app backend is built around Convex, with Convex auth and database integrated directly into the product architecture. That gives the app a more purpose-built live data model than forcing the main experience into a Supabase- or Firebase-style backend pattern.

Built for reliability, not just launch-day hype

For a live game app, uptime and responsiveness matter. Lackin is being built by an always-on team with a backend shaped around real-time product behavior, so fixes and improvements can move quickly when gameplay pressure is highest.

Features can land in days, not months

The recent product cadence already shows that speed. On March 31, 2026, group settings expanded into deeper admin controls, and on April 1, 2026, replies, Arsenal, and smarter map controls landed right after. That kind of two-day iteration is part of the product culture.
