Server batches
Levels arrive in batches. After download, they live on-device and can be replayed without network connectivity until you choose to refresh.
Round overview
Downloaded Levels are refreshed from the Echo Beam backend and always occupy round 5 in the game. On mobile platforms, access is gated by a voluntary rewarded ad; once earned, you can pull batches of stages from the server and play them offline.
These puzzles follow the same live-play rules as the Custom Pack: mirrors stay visible, quotas apply when specified, and collectibles plus teleports appear based on the downloaded data. Clearing progress or deleting downloads can be done from the Level Downloader screen inside the app.
Key elements
Rewarded ad unlock
Mobile builds request ad consent and, when granted, let you watch an opt-in rewarded ad to unlock the download button for a limited number of batches.
Live-play rules
Mirrors stay visible and rotatable; quotas are enforced when provided by the downloaded JSON. Teleports and collectibles behave exactly like in earlier rounds.
Reset & replace
You can delete downloaded levels and their progress from the downloader screen. Fresh downloads overwrite previous batches and reset per-level outcomes for this round.
