Welcome Spencer Wood,
Usually when two or more games of the same limit are in progress and a player requests to move to another table he must meet all of the requirements for that game. In other words, he must have the minimum buy-in and he can not exceed the maximum (if there is one). If the house moves a player, then that player may maintain the chips that they had in play even if it does not meet the required buy in, this would also include an amount that exceeds the maximum. Sometimes when games are breaking down, management is forced to consolidate several short handed games down to a reduced number. So a good rule of thumb (it keeps a lot of players from jumping from table to table) is to stick with this formula. Players that leave a game after a big win and want to come back to the same game must be gone for at least one hour, or they are required to buy-in with the amount they cashed out. You can see where these rules might be tough to enforce, but it has never been a problem that I know of.
Something else to consider might be to decide if you want to have balanced tables or use the main game with one or more "feeder tables." I prefer to balance but, many rooms use the feeder because they always want at least one full table. Example; Three tables spreading the same game, main game has 10 players and the first feeder might have 10 and the second feeder is in trouble when they get down to 6 or less. If you were using a balance with a total of twenty-six players, you could have 9 at two tables and 8 at the other. The balance would guarantee that no table had two more players than any other of the same game. We used to use table change buttons and if the player passed when asked to move they had to give up the button. In the wee hours of the morning, on a graveyard shift, when we knew that the games were going to break down, with no chance of attracting new players, I always liked the balance the best. I found that if we had three tables and we were at about twenty-two or twenty-three players, we would draw cards to see who would move and who would be first on the waiting list. Somehow, players were always more receptive to the luck of the draw as opposed to telling them they had to sit out because they were the last one seated by a minute or two. At times, we would actually make a table 11 handed to satisfy our early morning customers. I hope this helps.
