Correction 1, the 1956 / 1972 / 1983 confusion. Some Plinko pages imply the segment dates from the show's 1956 debut or from its 1972 format reset. The Price Is Right premiered in 1956 and adopted the One Bid, Pricing Games and Showcase Showdown structure in 1972, but the Plinko segment was first played on 3 January 1983. Legacy phrasing such as "First released in 1956… Since 1972… Plinko" is retained here only to identify the error; the corrected date is used throughout the article. (Updated.)
Correction 2, "no memory" versus "record tables." Provider marketing sometimes suggests a results board helps players "develop a winning strategy." A round-history table is useful for tracking turnover and volatility, but because drops are independent, it has no predictive value. The corrected reading is applied in Sections 3 and 7. (Updated.)
Open data gaps requiring further evidence. (1) No Plinko-specific behavioural study on player expectation during the ball's descent. (2) No Plinko-specific mobile-engagement study; statements about ubiquity and exposure are extrapolations. (3) No universal cross-provider probability for the 1,000x outcome. The figures cited here are tied to a specific 16-row high-risk simulation and to Spribe's documented tables.
