Rock | Paper | Scissors is a very old game. Like the prisoner's dilemma when played repeatedly complex patterns of play can develope. But I haven't coded any of that - I just wrote a simple interface for now. It looks pretty and is an example of minimal UI design.

In the future it will be easy to add new computer agents with different play styles. For now there are only two.

I like the UI, especially those "fuzzy" transitions between button states.

I have one suggestion though, don't use '%INCLUDE%' in the paths - it's simply unnecessary (let people set their INCLUDE environment variable with the proper path to the FASM includes directory).

I forgot why I was using %INCLUDE%. Think one of the six editors I'm using needs it. Or there was something else maybe. Removed.

I'm not really that lucky, the Test agent is predictable.

Yeah, seems that always directly after the program start the stone is the first correct answer. I think you may change the random number generator you've used there. To seed it you may use not only the timer but also such "physical" factors as the coordinates of the mouse pointer, maybe also content of some chosen parts of graphical memory or such.

Both windows and Linux have good[1] random number generators built in. There is not really any need to roll your own unless you are trying to learn or something, otherwise use the OS, that is what it is there for.

[1] By "good" I mean not-predictable and cryptographically secure also. But it is not perfect, naturally, because it is based upon algorithms and some external random events as seed material. For better quality randomness you would need to go to a proper hardware solution, but this would likely be extreme overkill unless you are dealing with banking transactions or similar things.

Test agent is just a loop of 32 moves.

Random agent ues Park-Miller, seeded by RDTSC. Which is sufficient here. Random is far from optimal against human or other non-random agents.

Some Japanese researcher created a robot that plays using a high-speed camera to detect human movement and plays perfectly.

bitRAKE,

AGENTS symbolic constant isn't used outside ubiquitous match L,AGENTS { irp T,L \{ expand/iterate combo, then it could be fixed instead (to drop those matches).

Add AI difficulty when implementing it. Like this:

Thanks, baldr, I was thinking on moving it to the Agent files - just didn't do it. So, just the order of includes would determine Agent order. Then I thought there could be a benefit to have different orders for each. Switching to FIX is much easier on the eyes.
