You can see the total points a specific challenge contributes to your score. On the Challenge Card, the number in the upper left-hand corner displays the total Challenge Points the challenge grants at its current rank.
However, it is important to note that this number represents the cumulative total value of the challenge, not the incremental points gained upon leveling up. For example, if a challenge is currently at Platinum (worth 40 points) and you level it to Diamond (worth 60 points), you gain 20 points, not 60. The points are awarded incrementally as you clear each tier from Iron to Challenger.
Upper Left Corner: Shows the total points the challenge contributes to your overall score at its current tier.
Tier Values: Points per tier are fixed (e.g., Iron: 5, Bronze: 10, Silver: 15, Gold: 25, Platinum: 40, Diamond: 60, Master: 100).
Incremental Gain: The points you actually earn by leveling up are the difference between the new tier's value and the previous tier's value.
