A party game played across several phones at once
One app, two games. In PieceRelay everyone solves their own fragment of the same photo, then you lay the phones side by side on the table and the whole picture is revealed across every screen at once. PanicRelay turns the same room into a bomb relay: defuse it in time, then pass it on.

Open testing on Google Play
The game is available on Google Play through the open testing programme. You join with a single tap — no invitation, no code, no waiting list — and it installs exactly like any other app. Open testing means both games are already fully playable from start to finish while we keep polishing them, so if something goes wrong, please tell us.
Co-op mode
The photo chosen by the host is cut into as many fragments as there are phones in the room. Everyone solves their own fragment on their own screen, then the whole group arranges the phones on the table into one large picture and reveals the finale: the full photo, a video, or a message spread across every screen.
How PieceRelay plays
Timed mode
The bomb lands on one phone and the countdown starts. Before the fuse burns out, that player has to solve their puzzle and then drag the bomb with a finger onto the next phone. If anyone runs out of time, the screens explode and the round is lost.
How PanicRelay playsYou need no board, no cards, and no extra equipment — just the phones already sitting on the table. The app works in English and Polish, needs no account, and the host decides how long a round lasts: anything from 10 seconds to 10 minutes.
They enter a game name and a nickname, set the round time limit and the puzzle size on each phone — anywhere from 2 x 2 to 6 x 6 pieces. Finally they pick a photo: from the built-in catalog, from the phone gallery, or straight from the camera.
The host lobby shows a QR code that players simply scan. Anyone who prefers can type the six-character room code by hand instead. A single room holds up to 12 players.
The app splits the photo between the phones and gives each one a different piece, scaled to that screen. You rearrange the tiles by swapping them with your finger, with the countdown and your move count visible throughout the round.
Once the phones are in place, you confirm the touching edges by tapping arrows, and the device in the middle starts the finale. From then on every screen plays as one: the full photo, the host video, or a message stretched across the whole table.
The game works best wherever a group is sitting around one table with fifteen minutes to spare. Below are the occasions it fits, along with what to use as the puzzle photo and what to show at the finale.
Use a photo of the birthday person as the puzzle and type your wishes into the finale message field. Once the phones reach the table, the birthday card reveals itself — instead of yet another chorus of Happy Birthday.
A photo of the couple becomes the puzzle, teams race through several rounds, and a video you recorded earlier plays at the finale. A good way to get the evening going while people are still getting to know each other.
Split the group into teams, use a photo from the last offsite, and set up a race over three rounds. The rules take a minute to explain, and to win, people have to push their phones together and actually talk to each other.
An old family photo, several generations at one table, and shared wishes at the finale. It helps especially when part of the family only meets once a year and the small talk runs out fast.
An old class photo as the puzzle, and the graduation year or a class motto at the finale. The photo starts the stories by itself, and the evening is long enough for everyone to install the app.
The host picks a photo and the round settings, while everyone else scans their QR code or types the room code. In team games each team gets its own code, so players land in the right team straight away.
Every phone receives a different piece of the photo and its own countdown. Players solve their fragments in parallel, and the app shows live who is already done and who you are still waiting for.
The phones go on the table and you slide them around until the fragments line up. The host taps “Verify”, you tap the arrows on the touching edges, and the device in the middle launches the shared finale.
PanicRelay uses the same online rooms as PieceRelay, but swaps the calm assembly of a picture for a bomb relay. You can play as a single group or set it up as a race between teams.
Before the start they choose the puzzle size and how time is counted: a separate limit for each player, or one shared pool for the whole group. They can also switch on teams and attach a video that plays once the bomb is defused.
A bomb with a burning fuse appears on the active player's screen, and moments later gives way to the puzzle. Everyone else sees “STAND BY” on their phone and counts down along with them.
Once the fragment is solved, put the two phones edge to edge. The player holding the bomb slides it off their screen with a finger, and the receiver pulls it in from their own edge — the bomb literally moves from hand to hand.
If everyone makes it in time, the bomb is defused and each phone shows one part of the final code — arrange the phones so the code reads from left to right. If anyone runs out of time, the screens explode. In team games the round goes to the team that defuses first.
