<p><strong>Accordion</strong>  </p>

<p>According to one of the biggest player on the solitaire market (SolSuite), the game of Accordion (one card at a time version) has a chance of winning in about 1 of 200 games, i.e. 0,5%</p>

There is probably a difference in the win percentage. If you lay out the entire deck first, you have perfect information about which moves are most beneficial. By flipping cards one at a time and making decisions as you go, you may make a choice that in hindsight was worse (i.e.: your piles could have been more appropriately condensed).

I suspect that there some difference in the rules between this Accordion and the one in the answer that state only 0.5% winnability.

<p>At least one of each three games can be won in the version where you lay out the entire deck. Just follow these strategy tips:</p>

<p>You should select four cards of the same rank, clustered near each other and near the end of the layout. The strategy is to try to get all four selected cards to the end of the layout and never cover them with anything else until the very end of the game.</p>

Are you estimating a 1/3 solution rate based on personal experience?  Or some database?

**Accordion**

At least one of each three games can be won in the version where you lay out the entire deck. Just follow these strategy tips:

You should select four cards of the same rank, clustered near each other and near the end of the layout. The strategy is to try to get all four selected cards to the end of the layout and never cover them with anything else until the very end of the game.
