The solitaire rules in this game are different than the free Windows Klondike version we're familiar with. The number of playable cards you have varies in each level and you can only go through your deck once. Once you have a brooch you can shuffle around the playable cards and the cards on the table. If you use an ability, it has to recharge before you can use it a again. While the brooch is handy, we found the cupid and phoenix abilities that remove table cards more helpful.
Eurogamer:
"Confession time: I really love playing solitaire. I don't love it the way I love other games. I don't admire the cleverness of its design, I'm not particularly entertained by its mechanics. I love it with a deep, psychological need, an almost philosophical yearning. Of course I love clearing the cards when chance allows, enjoying the Pavlovian kick of tidying up at the core of so much gaming - but I also, in a perverse way, love it when chance allows me no such thing. It feels true. I need to be smart to win, but my loss might have been written in the cards from the start, which makes a win all the sweeter."
Regency Solitaire is an addicting and entertaining solitaire game that you can enjoy for hours and hours.
Looks like it's worth a go then.
