This is an excellent example of simple and effective gamification, which recalls winning situations belonging to the collective imagination and therefore creates recognizability and predisposition in the user.
The basic mechanism is for all intents and purposes an INSTANT WIN online enlivened up the moment the possible win is discovered, which becomes more intriguing and interactive.
In fact, the moment the user clicks, a SLOT MACHINE or WHEEL OF FORTUNE style animation starts.
This is not a skill contest, as the prize is in any case randomly assigned by the software programmed to distribute the prizes during the promotional period.
The value of this solution lies in the higher engagement rate, achieved through the greater interactive dynamism of the relationship between user and brand.
