Bowling — free ten-frame bowling game in your browser

Ten frames, two balls each, and the scoring is the real thing: a strike is ten plus whatever your next two balls knock down, a spare is ten plus your next one, and the tenth frame hands you extra balls to cash those bonuses in. A perfect game is 300. Nothing is rounded off and nothing is simplified.

Your ball needs two decisions and both are made by tapping at the right moment. The first tap picks your line from a marker sweeping across the foul line. The second picks your hook from a marker sweeping along a bar — left, straight, or right, and how much. Then the ball rolls, the pins hit each other, and whatever falls, falls. Free, instant, and it plays the same with a finger or the space bar.

How to play

• Tap once when the sweeping marker is on the line you want. That is where the ball starts.
• Tap again on the hook bar. Centre is a straight ball; the further out you stop it, the harder the ball curves. On the first ball, straight is usually right.
• Pins knock each other over, so where the ball enters the rack is the only thing that matters — there is no power control.
• Miss the lane and it is a gutter ball — no pins, no argument.
• Ten frames. A strike ends the frame early; otherwise you get a second ball at what is left.
• The tenth frame gives you a third ball if you strike or spare in it, which is how a 300 is possible.

What this lane actually rewards, measured

Ten pins stand in a triangle and the ball only ever touches three or four of them. Everything else falls because a pin hit it, which is why the entry point matters more than anything else — there is no power control in this game, and there does not need to be.

The lane was measured across 3,060 combinations of line and hook, and the gradient is steep. A ball starting in the middle third of the lane knocks down 7.4 pins on average and strikes 14.3% of the time, and it never gutters. From the outer thirds the same ball averages 4.7 pins, strikes 2.9% of the time, and gutters one ball in ten. There is no clever line out by the boards here. The middle is where the pins are.

The hook is more interesting, because on the first ball it is usually a mistake. Rolled straight, with the hook marker stopped in the centre, a ball averages 6.1 pins and strikes 6.7% of the time. Rolled with a full hook either way it averages 5.0 and strikes 2.5% — less than half as often. A big curve is not extra power; it is a way of arriving somewhere other than where you aimed.

What the hook is for is the second ball, and half your frames will need one. When the pins that survive are all on one side, a straight ball at them clips the front one and leaves the back. Start wide on the opposite side and hook across, and the ball arrives at an angle that can take a whole row. When two pins are left with a gap between them, that is a split, and most splits are not convertible — take the one you can reach. A nine-count you can rely on beats a heroic ten you get one time in twenty. If you want a different kind of aiming game, Darts is two-axis timing and Mini Golf is pull-back power.
