Collection challenge issues

If you play the "Easy 1" challenge for each of the Game Collections (Klondike, Spider, etc), you'll have 50 stars to use to continue with TriPeaks.

In the Mixed Collections, the first three challenges of Classic and Easy are unlocked, and the first challenge of Tournament is unlocked.

It doesn't look like it's possible to play one Collection straight through as you're trying to do.

What I meant to say earlier, is the following: I have had the third collection, Coral Cove, for awhile now, but am stuck on Pyramid (Hard Timed Card Challenge) and Hard (Klondike Timed Solve Challenge) in the Wild West Collection, and Klondike (Timed Solve
Challenge) and Pyramid (Timed Card Challenge) and Expert (TriPeaks Timed Board Challenge and FreeCell Timed Solve Challenge) in the Coral Cove collection. I wish there were tons more, so I could work on others while trying to figure out the ones I have yet
to accomplish. Any word yet on when that will be and how many they intend to put out?

The only achievements that seem challenging are the ones about the collectibles.

Have a practice on the combat challenge levels from the main menu,they really help.

new challenge levels are unlocked by collecting certain trophies.

I just finished collecting all the collectables and its still locked for me could be linked to challenge maps or new game+ maybe
