In Plinko, high risk means there's a greater chance of losing your bet, but the potential payouts are higher. Conversely, low risk offers lower payouts but a higher chance of winning smaller amounts. Your betting strategy should consider the risk level: high risk for potentially big wins but with more caution, and low risk for more consistent, smaller wins. The number of rows you choose to play also impacts this, with more rows increasing the randomness and potential payout.
