This is insidious practice.
Deliberately creating silly challenges that you then have to swap out.
They’ve created a new currency as a solution to a problem that they invented! They even tell you as much in the on screen tips “complete your challenges using swaps”
It’s underhand and is not OK…
What happens in few weeks when all the free swaps are gone and people get stuck on silly challenges?..that’s right, you’re funneled into buying more swaps. They’ve established them as a necessary currency but without actually saying it.
The challenges are supposed to be a way to reward gameplay…not to be yet another way to manipulate you to spend more real money.
This is despicable.
