Support for Echo Rooms

For help, email shayanm2002@gmail.com. Include your Android version, device model, app version, room number and the steps that led to the issue. Send a progress backup only if you choose to share it.

How a turn works

The square follows your current command. The circle repeats the command from two turns ago; the diamond repeats the command from four turns ago. Every move and wait advances the timelines, including a move blocked by a wall or room edge.

All actors move simultaneously against the doors as they stand before movement. All matching plates must be occupied to open a circuit. The plates update doors after the move, for the following turn. Actors can share cells, and a closing door does not trap or crush an actor already standing there.

Undo, hints and restarting

Undo has no fixed turn limit. Restart clears the current attempt while keeping the best completed route. A hint searches from the current positions and queues. If there is no route, undo to an earlier position. If a search reaches its stated limit, undo or restart before trying again. All sixty rooms are available from the chapter selector.

Keeping your progress

Open Settings and choose Export progress backup. Save the ZIP file somewhere you control. To move phones, transfer that file yourself, install Echo Rooms using the Google account that owns the app, then use Restore progress backup.

Restore replaces existing progress only after the complete file passes validation. Invalid or corrupt imports leave existing records intact. A failed destination write does not erase in-app progress, but the incomplete exported file should be deleted and exported again. Backups include all room histories and best routes; display and sound preferences remain on each device. The uncompressed backup limit is 32 MiB. Backups are not encrypted.

Controls and accessibility

Use the on-screen direction buttons, arrow keys or W A S D. Space waits; Z undoes. Room details describe the board in text. Actors have numbered shapes, so color is not the only indicator. Sound and haptics are optional. The game supports light and dark themes, Android text scaling and phone or tablet layouts. Board changes are immediate, with no ongoing movement to follow.

Purchases and refunds

Echo Rooms is a single upfront Google Play purchase. There are no in-app purchases, ads or subscriptions. For a billing or refund request, use Google Play's purchase history or Help flow; Google displays the applicable options for your purchase. Support cannot promise approval of a refund.

Licences and artwork

All room layouts, game rules, native geometric artwork and store graphics were created for this project. The architectural miniature on the marketing page is an original AI-generated illustration, not a gameplay screenshot. Screenshots show the working Android app.
