Updated to V8.5 with High Score Table
I've been working on an "arcade" style yahtzee game in Flash and used the Adobe Packager to create a neat cab file for it. You'll also require the flash lite player from Adobe. The links are below. There has been a recent update to fix a high score error so please redownload.
I've tested this a lot with family and friends on my Touch HD and to be honest I'm addicted to it myself.
If you like it but discover any bugs let me know and I will fix and repost the cab file.
