Bugfix release - 1.10.19 August 30, 2018 10:57

We are releasing 1.10.19 version. This is a minor bugfix release. Things which are fixed:

  1. Accuracy settings for ICM are now calculated based on % of the pot. This is useful if you are unsure what to input in accuracy settings when solving ICM trees. Just use the same 0.35% (or whatever other number) as in normal trees.
  2. It's now possible to copy-paste ICM structure.
  3. Error checking for incorrect numbers input in various fields. For example using a comma instead of a dot as decimal separator is now marked as error hopefully fixing many confusing problems.
  4. In node-locking view it's now possible to see a strategy scaled by weights of hands (same as "squares proportional to weight" checkbox in the main view) giving a good idea of what actual range is.
  5. More measures to prevent Windows from entering sleep mode when solving/saving trees during script execution.
  6. Default font settings are fixed. The problem was that after recent Windows update the default font randomly switched to less readable one. It is now fixed.

 We are also improving our installer/updater to make downloads speeds faster and more reliable. Customers in China should be able to use the new installer as well (the old one was often blocked). You can get it here:


Moving to Discord and version 1.10.18 May 15, 2018 22:22

Our Skype group was very popular over the years. Unfortunately Skype's limitations made it difficult to maintain. This is why we are moving to Discord. Main Discord's advantages over Skype are:

  1. Discord has no user limit (Skype was limited to 600 people which proved to be too little, we were forced to remove users regularly to keep it alive).
  2. Channels: it's easier to move thematic discussion (marketplace, hardware) to separate places.
  3. Better security/privacy.
  4. Way better interface.
  5. Better moderation/spam control.

PioSOLVER Discord is still quite new. To join please use the link:

We are also releasing version 1.10.18. This is mainly a bugfix release, main changes are:

  1. An option to show strategy in node locking using the visual options line in the main view (normalize strategy, show squares proportional to range). This was an oversight, now it's possible to see weighted strategies again in node-locking.
  2. A problem when create subtree config would fail on the river if "remove lines" were present is fixed.
  3. Improve script generation to ignore trailing spaces in paths.
  4. Minor fixes in aggregation reports.

As usual to get the newest version run the updater in your Pio folder. If you need a download link, it's here:


PioSOLVER 1.10.15 March 12, 2018 12:25

PioSOLVER 1.10.15 is now available. This is another bugfix release. Most people won't see any functional change. Some of the things that were fixed:

  1. Subtree configuration for some edge cases
  2. Aggregation reports are now a bit faster and have more error checks
  3. Checks for new version (About in the top menu)
  4. More checks for errors in tree config
  5. Convergence issues on some trees (mainly the ones with small initial ranges)
  6. A bug in eliminate path feature is fixed.

Run the updater to get the 1.10.15 version. If you don't have it in your installation folder you can find it here: (top of the page)

Have fun!

PioSOLVER 1.10.13 February 7, 2018 20:18

Version 1.10.13 is available. This is a bugfix release, many things were fixes, including:

1)Small saves with ICM didn't work correctly (recalculated street didn't contain ICM), sadly old saves didn't contain all the information so they will still produce nonsense. Please notice that solving was correct and the results on the initial streets in the saves are correct as well. Only recalculating streets not in a save (usually turn/river in preflop saves) didn't work correctly

2)Problems some people experienced when saving configs are fixed
3)The updater not working in some location (due to rare locale system settings) is fixed

We're also happy to announce a gift for all our customers: All PioCloud solutions are now free to download, here:

Unfortunately our friend who run PioCloud project can no longer continue due to personal reasons. He decided that the best course of action is to make the solutions available for all instead of just removing them.
Please notice that he will not be able to provide any support on those and they come come as-is, that is without warranty/support/explanation. Please respect that.
We feel they are still very valuable but we can't afford supporting a completely free (from now) product.

Just in case you are still running an older 1.9 version, the new installer, updater is available here: (top of the page)
