While all three patterns (Red, White and Blue) are “house” shots, they provide a variable range of difficulty. USBC Red pattern is designed to provide the greatest amount of forgiveness and be typical of conditions found in most bowling centers today. Of the three patterns, the Red pattern will yield the highest scoring pace for a typical USBC member.
With a much higher concentration of oil in the middle of the lane, the Red pattern allows bowlers to find more oil inside of target and more dry boards outside of target, often resulting in pocket strikes while missing the intended target line. This “typical house pattern” is the least challenging of the three.
A center's standard house shot/condition is considered the Red pattern. Additionally, all house patterns that are not Blue or White are considered Red by default. Therefore, there are no lane machine numbers posted for Red patterns. Click image to enlarge.
