21 is a fun game for two or more players. The players stand in a circle. The players count up from 1 to 21 together. On your turn, you can say one, two, or three numbers, starting at the next number in the sequence. E.g. the first player can say "1", "1, 2", or "1, 2, 3". Whoever says 21 loses. You can play just one game with a single loser and the rest as winners, or you can play a sequence of games where you eliminate the loser each round, and the player left at the end of the last round is the winner.

Wax Museum is a fun game. You can have two or more players. First, a night guard is picked, and steps out of the room. The other players have five seconds to get into their positions until the night guard reenters the room. If the night guard catches anybody moving, the night guard calls that person's name, and they are out. The object of the game is to move without the night guard seeing you move. The last person who is not out is the winner.
Heads Up, 7 Up is a fun game. Players sit in chairs, put their heads down, and their thumbs up. Some of the players are "pickers". The pickers roam around the room while the other players' heads are down, and they each pick one player by tapping their thumb. That player then puts their thumb down into their hand to keep two pickers from picking the same person.
Once all the pickers have picked, the pickers go to the front of the room, and the leader says, "heads up, 7 up". The players that have been picked stand up. Each standing player gets two guesses about who picked them. One standing players makes both of their guesses before it moves on to the next player.
If a player guesses who picked them correctly, they switch with the person who picked them. If a player guesses incorrectly both times, they sit down and the game continues. There are no winners or losers in this game.
Suspect is a fun game with two versions. First, you pick a detective, who steps out of the room. Then you pick a suspect, who everyone in the room knows, but not the detective. The detective comes into the room and tries to guess the suspect.
Meanwhile, the suspect will be melting people by blinking two strong blinks at them. The detective has two guesses to guess the suspect. In one version, all the players are sitting in a circle, including the suspect, and the detective walks around the circle and tries to guess. In the other version, all the players including the suspect and detective are walking around the room.
Once the detective has guessed their two guesses, if they guess the suspect or not, the leader will pick another detective, and the game starts over.
Four Corners is a fun game. First, the leader picks a counter. The counter turns their face to the wall and counts to ten slowly. In this time, the players go to one of the four corners of the room. Once the counter has counted to ten, the counter picks a corner without looking. Whoever is in that corner is out. The game continues until either there is one person left, and they are the winner, or the counter gets the last 2 or 3 people out in one go, in which case the counter wins.
