How to play

Tumblin’ Dice is a flick-and-slide board game — think curling, played with dice on a tiered wooden ramp.

Take your shot. Each team slides or flicks its dice down the tiered board, taking turns — just like sliding a curling stone toward the house.
Aim for the back. Where a dice comes to rest sets its multiplier: ×1 on the front tier, rising to ×4 at the far back and on the raised side towers.
Knock them about. It is fair game to bump rivals — shunt an opponent off their tier, or clean off the board.
Score the dice. Each dice counts its pips × the tier it sits on. Dice that slide off the board score nothing.
Highest total wins. Add up every team’s dice. Play to a target score, or run the official four-round game.

Set your teams. The score table holds a column per team — tap a name to rename, tap a dice to recolour it, tap the small × to remove a team, or Add a team below the table to add one.
Snap the board. Tap Snap the board and shoot the whole board straight down. The app reads every dice and tallies each team.
Check & confirm. Cameras aren’t perfect — tap any number to fix it, then lock the round in.
Watch the score build. Every round stacks up in the score table. Undo a round or clear the card from its header.
Teach it your dice. From a team’s dice, photograph them so the scanner learns their exact colours.

Pattern Recognition API

Page Turner Labs · OMR pipeline

Tumblin’ Dice is the public training testbed for Page Turner OMR — our Optical Music Recognition stack for live sheet-music score-following and automatic page-turn cuing. Same problem class as reading music: discrete symbolic glyphs on a structured surface. Every in-app correction feeds the OMR training corpus.

TabletopVision: lab D6/D20 dice, cards, meeples, scoring tracks — validates the backbone.
