1) Interchange
One of the most played games on my new online solitaire site is the game Interchange. Interchange is a 2 deck Forty Thieves type game (learn more about it here). It has been the subject of much study, with an article written about its strategy.
Interchange is a very hard game to win - it is very hard to win it even 1% of the time. Often you don't even come close. Therefore, several other games have been invented to make it easier to win.
2) Unlimited
The first easier Interchange variation is Unlimited. Unlimited is the same as Interchange except it allows unlimited redeals. Interchange has no redeals at all.
Interchange is such a hard game that even adding unlimited redeals doesn't make it particularly easy, but at least it gives you a fighting chance in most games.
3) Give and Take
Give and Take is a brand new game in Pretty Good Solitaire v15.20. It is like Interchange, but also with redeals. In this case, the first time through the deck cards are dealt 3 at a time from the stock to the waste pile, then there is a redeal, then cards are dealt 2 at a time, then another redeal, then cards are dealt one at a time until done.
Give and Take is a much easier game than Interchange, but much harder than Unlimited.
4) Breakwater
Breakwater is exactly like Interchange except that building in the tableau is down regardless of suit instead of by suit. This makes the game considerably easier as there are many more possible plays.
5) Forty-Nine
Forty-Nine changes the tableau building method, just as Breakwater does. In Forty-Nine, building in the tableau is by alternate color. This makes Forty-Nine harder than Breakwater (which is regardless of suit), but easier than Interchange (by suit). Even so, Forty-Nine is still not an easy game.

A very interesting write up. I typically like Solitaire v15.20 because of this give and take feature. You took time to explain this. Thanks a lot.
