Excellent work!  I've spent so many weekends as a teen, typing in games like this into my C64.  I really like the idea of incorporating the use of the mouse.  This is probably my favorite Klondike game on the C64.

Wow. Thanks a lot for this nice feedback. I initially looked at other C64 Klondike games and thought that can be done better (and with mouse). The tricky (and fun) part then was to make it fit in my 3 A4 pages listing  limit and that it plays fast enough in BASIC. Was a great project.

Great software! Thank you for your work.

Unfortunately, I seem to be unable to move a card from the foundation to the tableau in klondike solitaire. Is this by design or is it an oversight?

Thank you. The feature to move a card back from the foundation pile to the tableau I left out by design (also own to my listing limitation to a maximum of three A4 pages). So if you run into a rare situation where a card on the foundation pile could have helped you then play the same number (seed) again and don't put that card onto the foundation pile too early. I hope that helps.

very good

Thank you. 

Very good job, thanks for another game for mouse 1351! Keep up your great workings! :)


Thank you for spreading the word <3

Not a d64. Ignored.

fixed :)

This is meant to be a bumpy nostalgia ride. And yes, it will take some time and patience to type it all in. But the reward in the end is higher than just playing a new version of Solitaire. You will see.

I just finished typing in Blackjack and fixing my typos. So much fun, thank you!! 

Very happy that you enjoy the listings. How about a game of dice next?

Sounds like fun. :) I remember playing Yahtzee as a kid with the family and having lots of fun, but I can't remember how to play. I'll have to brush up on the rules.  

Here is a short tutorial how to play Yahtzee:

Thank you.

BTW: Please note that in Blackjack you can also revert the stake by using F2, F4, F6 and F8. Just in case you didn't find out yourselves.

This is awesome - I used to spend hours and hours typing in listings on my VIC20 and C64 back in the day. This is really brining those memories flooding back. Of course back in the 80's I didn't have to contend with wearing varifocal glasses but I'm sure I will manage. The use of the checksum tool is a stroke of genius which will hopefully ensure I have a working game of solitaire at the end of it all! Just waiting for my C64 to come back from being re-capped and then I'll get stuck in!

Thank you. I hope you will have a good trip down the memory lane and will enjoy the working game. I had fun testing, which is a good sign. And let me know when you struggle too much. There is always a way.

Please note that the checksum tool installs itself in the tape buffer area. Therefore only save to disk is supported. If you want to save to tape then use the following pokes to deactivate the checksum tool:


Before running the typed in program it is also strongly recommended to deactivate the checksummer  (or better reset the computer) since the tape buffer may also be  used by the program logic and without deactivation it may crash the computer.

I'll be saving to floppy disk thankfully :) I've successfully got the checksum tool working now. Ironically the tool doesn't work on itself - I made several mistakes typing the numbers in which kept resulting in an out of data error! 

I've ordered myself one of those magnifying rulers which will help me to both read what I need to type and keep track of where I'm up to (I'll be printing the listings out to work off).

Will be great to eventaully have another program that I can use my 1351 mouse with too!

Am I correct in thinking that I only need to type in the shorter v2.1 listing if I'm not bothered about joystick compatibility?

Both work, but if you have not started, I would recommend to use the latest V3.0 listing. The v3.0 mouse version is actually a little bit shorter than the v2.1 listing because of some optimizations and it makes sure you have enough BASIC memory left in case you would like to experiment and/or add your own optimizations. And for the mouse version you can omitt the joystick replacement code on page 5. The Joystick part is not additional but replacing parts of the program. I hope that helps.

Thank you for working on a Joystick version for Solitaire. I'm still inputting the mouse version. :) 

I hope to release the Joystick version tomorrow. Fire button double-click will act as right mouse button (to bring cards directly to the foundation pile).

Please download the latest Solitaire2021.pdf, now with additional Joystick enablement code

Thank you!! Solitaire Mouse version worked great on my MiSTer FPGA Commodore 64 core. I ordered a Commodore PS2 mouse adapter so I can give it a go on my Commodore Ultimate 64. :) The game looks good and plays very well.

Great, educational way to share c64 games. Thank you very much! Solitaire looks great!

Thank you.

Tip: For Solitaire use the following numbers to have a guaranteed winner:

1             = Can be won with both Draw 1 or 3 card(s)
31423 = Walkthrough (fantastic card deck) :)
