1. Choose the campaign type "Memory".
2. In the step 3, "Cards", instead of putting twice the same image, put matching but different images.
E.g. A product and its price // Couples: Brad & Angelina // A founder and its company
3. You can choose up to 15 pairs (not recommended as this is 30 cards to match).
4. You'll identify winners based on number of clicks.
5. The rest works exactly like any other Qualifio campaign: anonymous or identified, welcome and exit screens, virality options, etc.
