• ✓Stamped out of the same floor as the bean-bag ring — what changes is the piece, how many, and the dots on them
• ✓Both ends carry exactly one to nine, so a round lost was never a round dealt unfairly — and verify:toss checks it every run
• ✓The dots use dice and domino patterns, which a child reads at a glance — counting them one by one takes longer than the shell stays in the ring
• ✓The score is the sum of the dots, not a count of pieces — so knocking the other end's nine out beats nudging your own three in
• ✓The floor is sand, not boards: vertical plank lines on a beach quietly move the game indoors
• ✓The pieces are painted turtles in two poses — tucked in, and head and feet out — both framed on the CARAPACE, so nothing jumps when one is swapped for the other
• ✓Lie still for 25 seconds and a turtle rocks, puts its head out and walks out of the ring — so somebody has to call the round
• ✓A walking turtle can be flicked straight back in, and being flicked tucks its head away and restarts its clock
• ✓A walk is not a velocity: if it were, the round could never be counted, because a round is counted when everything has stopped
• ✓The sand is still drawn in code — a floor painted from directly above is still to comeplanned

✓ = done · ☐ = planned. Every game is built one step at a time like this.
