Question: Are there duplicate numbers in this set of 50 cards so that there could be more than 1 winner at a time?
Document: Nice set. Yes, some of the shutters were &#34;stuck&#34; in the open position but that is easily remedied. As the game cards are passed out for the first time, have the players close and open each shutter on the card a few times. After this initial break-in the shutters work just fine. You can still use your own ball-cage to call out the numbers  if you like but the included calling cards work just fine.
We have a company picnic every year and our employees love Bingo. This set works perfectly for our needs. The Bingo cards instead of the balls is terrific. So much easier to handle. The only thing that could make it better is if it came in its own plastic or wooden carrying case.
I ordered on Monday. It arrived on Thursday. I paid for fast shipping. Our church seniors were taking a 9 day bus trip leaving on Saturday. I was so glad it arrived in time to take with us. We had a lot of bus time to kill and bingo was a great way to do it. This is a nice bingo set and the shipper got it to us as promised.
I purchased this set to donate to a local nursing home. The activities director was so happy to receive it, as many residents enjoy the game but have a hard time picking up and holding the poker chips they had been using. Additionally, several of the little balls had gotten lost and the director had to remember which ones they were to call them out randomly throughout the game. With the card deck and masterboard, the director had more time to assist the players. This set was the perfect solution.
The cards were perfect. I will get many years of use. They are sturdy and the shutters are very good.
The plastic shutters on several of the cards do not slide and come out.I bought it for games on motor coach tours. The quality of the slide cards are not as good as my previous ones.
The game is great. My family and I had an awesome time during the holidays. It is my mother-in-law's favorite game. She had a blast!
Everything arrived on time and was just as expected. Everything came in perfect condition. Other reviews stated some of the slide shutters were off kilter, but mine were just fine.
Bingo Cards do not have wood grain pattern as described. This is not a major issue but the description should match the product. Some of the sliders are twisted on the cards making them difficult to move. In reading reviews prior to purchasing the cards I figured it was more of an operator error. I was wrong, it is a manufacturing defect. I would not recommend the cards for senior players as they will have difficulty sliding many of the tabs. Fortunately we are not seniors and simply played through our frustration.
This Bingo set is Sturdy, convenient, and lots of fun to use! I would recommend to use in large group settings.
