The more emotions a player experiences, the stronger their desire to return for more. This approach positively impacts Day-over-Day (DoD) retention, motivating players to come back daily.
In Solitaire Grand Harvest, an additional
daily bonus was introduced as a generator of positive emotions.
A Fresh Experience with Familiar Mechanics. The bonus mechanics are similar to existing ones in the game, making implementation less labor-intensive. However, the design is distinct, giving players a sense of novelty.
Double Rewards on Login. By adding an extra bonus, players receive double rewards when logging in. This immediate boost of positive emotions encourages them to return.
The Thrill of the Unknown. The additional bonus offers rare rewards, with the contents unknown until received. The excitement of potentially getting something valuable motivates players to log in daily for their next reward.
Time-Limited Rewards. Most rewards are time-limited bonuses that activate immediately upon receipt. Players are reluctant to waste this advantage, keeping them engaged in the game for longer sessions.
