The boardwalk arcade alley: roll a ball up the lane, it jumps off the hump and drops into a ring — 10, 20, 30, 40, the 50 in the middle, or a tiny 100 pocket in the corner. Pull back and let go to set the aim and power, or hold to fill the meter. Nine balls per machine: reach the target to move on, where the rings shrink and start to slide. Leftover balls score double and three 40s in a row light up a hot hand. Free, no sign-up — play right in your browser.
