What easy-to-use simulation tool do you recommend?

I built bridgedummy.com, and I’m wondering what other options are available.

I use the 'dealer' software along with my own scripts to simulate hands. The version I use can be found at https://github.com/d...aler-Version-2-.

I used the original Tcl implementation, but this one is also pretty good.

BBO offers Dealer online, but a couple of years ago they suppressed without explanation the version that implemented the 'tricks' function essential for double dummy simulation. I still fail to understand why, it would restore some prestige and credibility to an aging platform and ecosystem.

Is it easy to get either of the two standalone versions mentioned working with the tricks function on Windows 11 (assuming one does not have legacy source or binary for bridge.exe) ?

The link I provided has it included, though it's called the 'dds' function in this version (Double Dummy Solver). If you're interested in some example scripts, I have built up quite the library over the years.
I like this version because it's reasonably fast - about 20 deals solved double dummy per second on my machine. I know of some other branches and can provide links to those if you're interested, but I do think they are generally slower.

I like Piotr Beling's bdeal. Doesn't have a huge number of fucntions but it has most you would need along with a few statistics gathering functions
I haven't explored the API to expand it at all
I can't comment how it compares computationally, functionally, or precision with other solvers though - I am of the not totally uninformed views that greater complexity does not imrpove many predictions
I like it and it does not take much work to write more complex scripts once you work out the tricks
It doesn't have a losers function but I kind of wrote myself one etc
