A bowling game kit suitable for use on a sand beach comprises a backstop and an elongated flexible rectangular sheet of material connected at one end of the backstop and having one or more target holes adjacent the backstop, which can be in register with buckets situated in depressions formed in the sand. The system can utilize a deterministic scheme to detect an interference by a spurious frequency and correct the distortion effect or utilize a mixed signal processing architecture to avoid the occurrence of spurious frequency contamination. The law includes an energy absorption phase followed by a retraction of the piece. The apparatus may also include a counter to determine a count of rising and falling edges of the single-ended signal based on the oversampled clock signal.
