The game is played with three balls, two white and one red, with one of the white balls having a small red dot, or spot, to distinguish it. If you're having trouble, you may be pushing adjacent pins up past the shear line as you pick a pin, causing them to be overset even before they start to bind. Eventually, you'll be able to comfortably pick the locks with five and six pins installed. You also need six object balls, which are numbered, along with one cue ball. There are locks with two, five, and six pins in each keyway, but the keying codes aren't labeled on them. Note that while many locks pick predominantly back to front or front to back, there are exceptions, and you may find that the binding pin stack "jumps around" from the back to the front to the middle and so on. The cue ball is white, while object balls come in different colors and numbers, depending on the game being played.

This technique requires a great deal of practice to master, but has the surprising property of sometimes being more effective against better made locks. Surely consistency in practice will accelerate your progress. It feels much as it does when binding and unset, but will not set (since a binding pin can only move up, not down). Finally, lift the pin that sets first very high before you apply torque. Now release torque and try again, but this time lift the pins as little as you can when you test them, while still distinguishing between the two states. While the pin tumbler cylinder is by far the most popular door locking mechanism in the United States, it is not the only kind of keyed lock in common use. The most common security pins are the "spool" and "mushroom" top pin designs, which are thinner in their mid-section. Do not assume that the next pin will be adjacent to the one you just set. You could build an engine at either pole and this wouldn't have any effect, but anywhere else and the constantly changing angle of thrust will cause the Earth to behave somewhat like a loose Catherine Wheel-type firework. It gets better. Even assuming the Earth did move by some significant distance when everybody jumped, just think about it: it'd move right back again!

The multiple peaks allow several, or even all, pin stacks to set simultaneously. Because there are two independent shear lines, there is no way to control, or even tell, at which shear line a given pin stack sets. You should always know which pin you're working on at any given time. While pin-at-a-time picking is usually the most reliable way to open a given lock (and the skills used essential for mastery of other techniques), raking can sometimes open a lock more quickly. Apply very light torque while energetically moving the sawtooth rake in and out of the keyway. Sawtooth rakes, such as the Peterson "Ripple" and the Falle-Safe rakes, have 5 or more very acute peaks along the length of the pick's edge. The Peterson "Reach" deep curve pick works well for this keyway, what is billiards pivoting from the bottom of the keyway at the front. The lock will never pick open in this state; you must release torque and start over.

Caudle, it's all over now; you've gone to destruction. An important skill when picking is to recognize when this has happened so you don't waste time before you start over. So dedicate regular time to practice and focus on specific areas you want to improve. It will take a bit of practice to find just the right technique. Look on TV, YouTube, Twitter, and Facebook; you can find groups and channels dedicated to the game along with digital versions of some of the more popular variants. Once you've mastered the two pin lock and can distinguish reliably among pin states, you should have little trouble with a three pin lock. When the pin stack truly sets at the shear line, it will feel like an ordinary set pin. Pin stacks with partially set spool and mushrooms, on the other hand, will feel a bit different. The usual scheme for master keying involves using more than one cut in some or all pin stacks (this is accomplished by adding additional pin segments). Overset/binding. The cut in the pin stack is past the shear line. Practice distinguishing between the pin states and then finish picking the cylinder.
