“There is no universal engagement mechanic because there is no universal reason why players engage. Some respond to progress and the satisfaction of completing a goal, others to competition, while for others it is anticipation that keeps the experience exciting. That is why we see Challenges, Tournaments and Jackpots as three different tools doing three different jobs. For operators, the real opportunity is not choosing one mechanic over another, but building an engagement mix that can activate different motivations at different moments.”
