Squeeze into a tighter tableau and redeal the waste as often as you like in this Ali Baba spinoff. One deck, medium difficulty, and a 40% win rate.

Cassim Solitaire is Ali Baba Solitaire with a smaller tableau and unlimited redeals. Cassim was Ali Baba's brother and the captain of the Forty Thieves in the One Thousand and One Nights.
Medium-difficulty play here nets about a 40% win rate. You play with a single deck, and doing well takes both skill and luck.
Big Forty Solitaire plays in much the same style.
If you enjoy Cassim, the wider Forty Thieves family of games is worth exploring too.
If you run into anything odd or have an idea that would make the game better, please contact me.

4 foundation piles: Build up from Ace to King in the same suit.
7 tableau piles: Build down in the same suit. Sequenced groups of cards in the same suit can move together. Any card can fill an empty space. Each pile starts with four cards, dealt face-up.
Stock: Click to turn over one card at a time to the waste. Redeals are unlimited.
Waste: The top card can be played on the foundations or tableau.
There are four foundation piles.
Any ace can start an empty foundation pile.
A card can be added to a foundation pile if it's one rank higher than the pile's current top card and shares its suit — so the only card that can follow a 4 of clubs is a 5 of clubs.
The top card of any foundation can be moved back into play if another pile will accept it.
Seven tableau piles, four cards each to start, all dealt face-up.
A card can be added to a tableau pile if it's one rank lower and the same suit as the pile's current top card — so the only card that can follow a 9 of diamonds is an 8 of diamonds.
Any tableau card not covered by another is free to move to a foundation or another tableau pile.
Any card can fill an empty tableau space.
When a run of cards is all the same suit, high to low, you can move the whole group from one tableau pile to another.
There's one waste pile, and the rest of the deck makes up the stock.
Click the stock to deal one card to the waste. You can go through the stock as many times as you like.
The top card of the waste can be played to the tableau or a foundation.
