Competitive Cribbage - Autumn 2021 Season

Welcome to the Autumn 2021 Season of Competitive Matchmaking for Cribbage Pro! Competitive Cribbage Summer 2021 (Season 5) has ended. It is always great to see players on the Top 50 to end the season that were not in last season. Somehow you all manage to play more and more matches each season, setting a new record for players and matches this last season yet again, so the competition is definitely fierce!

Don't forget to tell your cribbage friends about competitive cribbage, and of course the chance to win the prizes! You have my permission (ok, a request) to brag to your friends about your placement and challenge them to see if they can do any better. In any case, thank you to all who were able to participate in this great game of cribbage.

In 1st place, we have (yes, again) "iPeg". 2nd place is "BigD4Life" (up from 23rd last season) and in 3rd we have "dkatz1877" (up from 9th last season). A close call in 4th is "236Postie", so a special shout out for that run at the top. This season's other honorable mentions go to 5th place player "ernie313" who came up from 30th last season, "Br1Guy" who was 21st last season and now 8th, and "DertyFerd" in 10th rising from 44th. I believe those improvements certainly represent some real hard work to get there. There were a lot of other big improvements again this season, including several new to the Top 50, so congratulations to you all as well.

I do have some potential inside information that may indicate iPeg could be taking a breather this new season. If you were sitting out and waiting for your chance to make a run at it, this may be your chance, or I suppose iPeg reads this and decides to not sit out! Should be a fun and exciting season either way. With that said, iPeg's accumulated Gold so far should make for a fun opponent in the Cribbage Contests system if you are looking for a way to make some extra cash. Maybe send iPeg a friend invite/challenge to put those winnings to good use! (sorry iPeg, you are about to get spammed with friend requests - the price of fame and fortune).

As with past seasons, everyone who finished the season in the Top 50 ("Recent" list), have been awarded both a special in-game "board peg" as well as Cribbage Pro Gold that can be used in the Cribbage Pro Contests system and then redeemed for cash (awards must be used at least once in a Contest to be cashed out to USDC, see the full terms and conditions for details). The top finisher is awarded the "crown" board peg, and all others in the Top 50 are awarded a "star" board peg. These pegs are shown to everyone when playing in online multiplayer games, and they are permanent, so if you see your opponent has one of them you can know that they have earned it by finishing in the Top 50 in competitive play. The Cribbage Pro Gold awards are as follows (not cumulative):

  • 4 Gold for Top 50
  • 7 Gold for Top 25
  • 10 Gold for Top 10
  • 20 Gold for 3rd Place
  • 30 Gold for 2nd Place
  • 50 Gold for 1st Place
Remember to complete your 10 matches per week. See the FAQ for details. Play early, and play often!

Here was the final Top 50 for Summer 2021 / Season 5:



  1. Thanks Fuller Systems for providing a very challenging format for competitive players! Rather than risk suffering from CWS (cribbage withdrawal syndrome), iPeg will participate again this season. Good luck to all the players!

  2. Let me add to ipegs comments.. The competition is by far the best implementation of matchplay cribbage that i've seen

    I look forward to seeing even more enhancements over the coming months!!

  3. Dear app master here's a recent issue that i have encountered. I have both wifi and data with great connection. i have had a a few games where the opponent goes past the 10 seconds and there is an exclamation mark on there photo and says time exceeded and it kept on going on for more than 8 to 10+times during the games yet the game is allowed to continue??? Sometimes it just stays on the exclamation mark and i get charged for the loss and sm not allowed to log back in for the penalty???

    1. Hi, connection problems are often complex. Remember that when it comes to play time, the other players connection will be a factor as well so that even if they play within the time limit on their device it may take a while to reach our servers and then back out to you. Our servers account for this, and that is why you may see it as exceeded on your side when it has not yet by the server calculation. That said, if you are given a loss, then that means it was seen as your side losing connection. If you would like more insight into ways to improve your particular connection situation, email us at support@FullerSystems.com and we can review your game logs and go from there.

  4. The end of match stats... Hand and pegging scores.... Do these refer to all 3 games or just the final game?

    1. For matches with multiple games in the match, like in Competitive Matchmaking, the stats shown at the end are for the entire match over all games played in that match.

  5. Enjoy the game, but so many games are determined by opponent getting 4 or 5 large hands against my 2 hands. I’ve skunked and have been skunked many more times than in normal play.

  6. Does the CR ranking system use any means to take the 'luck' out of the game? Or is the best-of-3 format used the only means?

    For example, if the winner of the match had >2.0+/pts per had hand more than the loser, you can assume that luck played heavily into their win (assuming the loser was still making the correct discards, which could be verified by the program), and that the skill (pegging) played almost no part.

    Should the result of this type of match carry the same weight as a match where the points/hand average was roughly equal between the two players and it came mostly down to the pegging to determine the winner?

    1. Hi, the short answer is "no". The multiple games played per match is what is used to help, but certainly nothing is perfect. There are some other ways to do ranking systems that we have some ideas about, but they look less like a traditional game of cribbage in various ways. We have a very strict policy that the game will never manipulate cards or anything else like that, so doing anything like that is off the table. Perhaps there is some math that could be done that can determine what part of a win is luck versus skill, but I'm not aware of any proven methods.

    2. Trying to credit a player for good decision making vs simply getting better than or poorer than average hands would be very tricky. Sometimes playing defensively results in lower pegging, lower hand averages, but may be the best strategy to win, for example. The bottom line is winning percentage over the long term. The best way to remove the “luck factor” is to play a large number of matches, so the cards dealt become statically balanced. Luck matters in any given game, but in 500 games, the most skilled player will be at or very near the top. “Strength of schedule” is applied also in the multiplayer competitive format, giving more credit for a win against a highly rated player (typically high winning percentage) vs one with a lower rating.

    3. Thanks for the reply.

      I'm just putting out some suggestions that I think could work. I'm not at all suggesting that the app should manipulate how the cards are dealt, but I do think that some analysis on the stats of each player could be done to determine how much luck was involved in the result of each match, and then use that to adjust how much weight the system gives to it.

      There's obviously some skill involved in the discard, as an inexperienced player won't make the correct optimal discards that a more experienced player will. But the system (or at least other cribbage apps do) should be able to analyze player discards to determine this and take it into consideration.

      If each player makes the correct discard 98+% of the time (this should be the case for all matches between CR 4000+ players), you can determine the luck of the cards based on their average points/hand. If there is a large differential between the average points per hand of each player (eg. 6.75/hand vs 8.75/hand) we can assume luck played a large part in the game, no? The skill part (pegging) did not have an affect on the result.

      I think there's a opportunity to look at such data and perhaps incorporate it into the CR ranking system.

    4. I would also be interested in statistical averages for hand, crib, and pegging for various players, both for the player and for their opponents. A very small difference, a 1/4 point per hand can make a big difference in winning percentage. I think there was a blog post about this previously, analyzing A,B,C,D player levels.

    5. @Sawyer More stats would be great. @Fuller is there any possibility of these type of stats being added to the app?

      I think it'd also be nice to see a snapshot of the stats from your last 500 games or so and how it compares to your 'career' stats and see whether you are improving or not. Your win rate can tell a lot but once you've played several thousand games it looks like it never changes.

    6. @XLNC21, we have a long list of things we want to do, and adding more stats on many different things is definitely on the list. Again, it is a long list, so I can't say when it will be done, but we do plan to eventually get to everything.

  7. @Sawyer you're probably right, it likely does even out over the long run and the skill does prevail in the win %. But a system that can identify the skill sooner would be an improvement, no?

    I want to clarify that I am not criticizing the CR system. It does seem to be very good at ranking players as it is, as the top CR 4200+ players I've played are without a doubt excellent players. I just thought there is a potential to possibly eliminate some of the luck involved in the ranking system. It's also possible what I'm suggesting would have no bearing on the overall standings in the competitive leaderboard at the end of every season.

    1. It is an interesting concept. Optimal decision making can be measured to a large extent. However, a vast number of players have a healthy winning percentage against the advanced computer (brutal) mode on the app. So the computer still needs some help in making optimal decision. There are so many subtleties in cribbage, it a wonderful game!

    2. @Sawyer, my position tends to be that "optimal cribbage" is searching for a unicorn. Just my personal 2 cents. However, I don't disagree that the strategy of the computer AI could be optimized in many ways. We generally don't do much to improve that because frankly it is hard enough as it is.

    3. One way to remove 'luck' would be to get all matches to be with the same dealt cards.. In a similar way to how Duplicate Bridge is played and scored..

      Just an idea..
