Puzzle dependency graphs in Compose. Hint pushes from the game-master's screen. Full-room resets that work cleanly between groups, every time.
Escape rooms live and die on turnover. A jammed reset costs you a group. A confused puzzle costs you a review. Northstar handles the choreography so the game-master can focus on the players.
Author the room as a DAG in Compose. Puzzle A unlocks B, which arms C, which reveals D. Polaris enforces the order.
Game-master types a hint in Cuemaster, it appears on the in-room screen — text, audio, video, or a triggered visual cue.
Group exits, GM hits Reset. Polaris re-cocks the mag-locks, resets the props, clears state, dims the lights. Ready for the next group.
Cuemaster shows the room from above: progress bar, current puzzle, hint history, time remaining, all live.
Easy/medium/hard variants, skip paths, custom endings. Compose has if/then for puzzle order without touching code.
Win rate, hint count, puzzle bottlenecks — all logged by HelmOS, queryable in Cuemaster. Tune the room from data.
