U mean custom games?
We got math trivia: basically putt a question in chat and whoever answers correct first wins. Works with every trivia.

Simon says: somebody is " simon" and will tell Ts what to do everything Simon tells them to do.
Ussualy started up by "Simon says I'm Simon, Simon says don't do anything Simon doesn't tell u to do, Simon says u have 3 seconds to comply to whatever Simon tells u to do"
And then he gives orders like "Simon says jump and remain jumping" or whatever u want them to do. And if they don't do it correctly they die. Important detail: they only do things that Simon tells them. So if u say "all Ts jump" they shouldn't be jumping.

Cliffhanger: get on an object off of the ground and let the prisoners unstuck at a side. Let them face away from the side(ussualy towards a wall) and flashlight on and facing straight up. Flashlight is so u can check where they face.
Then u let them go towards the other side without falling off. If they fall off they die, if they think they are close enough to the edge they can stand up and look around. Person closest to the edge wins a prize. If they look down before they are done they die As well.

Duckhunt: go to pool with diving boards that boost people up in the air. (Can also be done by jumping off of a high place and let them land in pool)
Goal of this is that the prisoners land in the water alive and try to avoid sniper (AWP) bullets while being in the air.
As long as they are in the air they can do whatever they want and Cya can shoot them as long as they weren't in the water (Only with AWP)

High/low spray contest: everybody has a picture that can spray and the person that can spray it the highest on a wall wins a prize. With low spray it would be the person who's spray is lowest that wins.

Parkour: do some tricks and jump from object to object. Try do some difficult moves and see if the prisoners can succeed in copying them. If they fail to do a jump/move they die.

Prize trivia: basically works the same as regular trivia but the winner gets an unknown prize which he can keep or pass.
IF he keeps the prize, whatever the prize is is for him. This can mean he dies or gets to chose a person to die, prizes are completely open for imagination. If he passes the prize the person who gets it passed to him will receive the prize.

Gatekeeper: the prisoners are in a room and have to try and get into another room. CTs will stand between the w rooms and will knife the Ts trying to go from 1 room to the other.
Details: CTs should knife in a way that they do the least amount of damage(left clicking in css) and can only knife them while they are outside of the rooms. Once they are in a room they can't be touched.

Soccer: regular soccer match. Select teams and first team to score certain amount of goals wins and other team dies.

Race: Ts are in a spot and for T to reach another spot that has been designated as the finish wins and gets a prize or whatever u want to give him.

Warday: not really a game but it's basically a round where u take 1 place as a war zone where CTs can shoot every T that enters it. The warday will expand at a certain time after which CTs can go all over the map go kill everybody.

Hide and seek: 1 team hides and after a certain time the other team will go find them. The hiding team can't shoot the seeking team.

Animal day: each person (of the Ts) gets to be an animal.
The animal can be chosen by the warden or by T himself depending on how u want to play it. If they fail to act like the animal they die. Some animals can be killed by Cya in the form of hunting. Example: lions, tigers, all kinds of exotic animals. They are given a head start and after that Cya can hunt them.

Talent day: everybody can show a talent that they have. If the guards like it they stay alive if they don't like it they die.

Jokeday: works the same as talent day. The Ts tell a joke and if the guards don't like it they die if they do like it they live.

Can't come with more games atm but I'll give u more once they come back in mind.

I really hope u meant this by games :/


Edit:

We also got ...

Odd man out: u have an uneven number of prisoners (ussualy a low amount. 3 is the easiest) and those will stand in a triangle.
At a time they will face somebody of the other Ts .
IF the majority face 1 person that person dies.

This can all be played by letting the prisoners perform an action. With 3 players it would look like this:
3 prisoners face away from each other and will have to jump or crouch by a certain time. If 2 prisoners jump and 1 crouched the guy that crouched is the odd man out and dies.

Primary,secondary,melee: personally not a fan of this " game"
Since it give the Ts only a small chance of survival and it is purely luck based. In this game the prisoners will face away from the warden and have to guess if the warden is holding a primary secondary or melee weapon. If they guess correct they live and if they guess wrong they die.
