Get every wheel to 9. A wheel on 9 is primed — one tick from rolling over. It turns amber and pays as it arrives.
Then feed the rightmost wheel (marked ▲). A chain only rolls leftward, so ▲ is the one place a single chain can reach every wheel. It glows brighter as the board fills.
A new digit = the whole board rolling over at once. Prime every wheel, feed ▲, and the carry off the left edge is your new digit — a perfect sweep, ×5 points.
999+1→1000
Watch the edges. An amber-glowing wheel is where this tile lands exactly on 9. A red-dashed wheel means this tile would overflow the board and cost you points — don't.
