When players are trying to knock down the six-pin, the target should be moved four boards to the right. . The use of the 2-4-6 system is applicable on all lane conditions, so players don’t have to worry about any problems that might arise when trying to pick up spares. The system is not as widely used as the 3-6-9 spare system, but it is one of the most popular basic spare systems. However, using the 2-4-6 method is the best way to avoid problems, and to accurately pick up spares in all conditions. The starting position will remain the same, but the target will change depending on the spare that must be made. Like the 3-6-9 system, players must adjust off the corner-pin line to pick up their spares on the other side of the lane. Two starting positions are used on the approach in the 2-4-6 spare system. Using the system can help players become more confident in there “spare-getting” abilities. The spare system can give bowlers many advantages.
The 3-6-9 spare system is the most commonly taught system, but the 2-4-6 system may be the most accurate system for picking up spares. The 2-4-6 system is not simple, so it is most commonly used by professionals. If the player is trying to pick of the 3-pin spare, then the target should be moved two boards to the right. In the 2-4-6 system the feet are not moved opposed to the 3-6-9 system. The two starting positions in this system are the strike starting position and the 10-pin starting position.
If a player has a strike-line (the yellow line) of 17-10, then that player can deliver the ball two more boards inside in order to knock over the next pin(2-pin for right-handed players, and 3-pin for left-handed players). For left-handed bowlers are trying to pick up the 10-pin spare, the target arrow should be moved six boards to the right. There are also two aiming targets in the 2-4-6 system; the strike aim and the 10-pin aim, used for all the spare combinations. Also, like the 3-6-9 system players can adjust the movements to fit their own personal bowling style, and create the most accurate way of picking up spare. In these instances, moving the feet can create problems in the 3-6-9 spare system. In this system the feet remain in the same place, and players must visually adjust the target. The targets should always be moved, but the feet should remain in the same starting place each time.
The 2-4-6 spare system is also known as the Swedish Spare System, and is usually recommended for advanced bowlers.
All players that use the 2-4-6 system should not move their feet, if they want to pick up their spares effectively. Players should visually target the two, four, or six boards off of the key line in order to pick up spares. Sometimes players aren’t able to move their feet because the ball return may be in the way, or the player might be playing on an end-lane, which is near a wall. The left-handed players who start from the far left side of the approach are able to use the 2-4-6 system effectively. The 2-4-6 spare system also works for left-handed bowlers. A four-board shift in the target will knock over the 4-pin(6-pin for left-handed bowlers), and a six-board adjustment will knock over the 7-pin(10-pin for left-handed bowlers). When using this system for picking up spares, the bowler must be able to bowl on the arrows, and able to bowl on the boards between the arrows
