Choose a PackDex™ room, see who is joining the prediction pool, then follow the opening from source record to card verification and receipt.
PackDex™ opening terminal ready.
The room is ready. Open the selected PackDex™ to move from source record to packets out, card verification and receipt.
Each room shows who is joining, the current prediction pool, pack formula, declared strike and recent close time. Select one to make it current.
Room participation, pool amounts and close times shown here are sample public-room data.
Every PackDex room makes participation visible before the opening: people joined, pool size and the current HIGHER / LOWER split.
Cards, values and the comparison against the declared strike stay together in one clear room receipt.
This is the minimum chain the app needs to make an opening understandable from queue entry to final comparison.
Keep the pack formula, source label and cost visible before the room opens.
Move from sealed cube to packets out, then keep the card reveal tied to the same room.
Return distinct card references and a recorded value for each opening.
Publish the final total and whether HIGHER or LOWER would have hit.
