Pirates tag. (you may know it as another game): but its when you get a bunch of mats out on the floor. It just like tag, where you have a person or two (depending on how big the group is) that is trying to tag all the other people. the catch is they have to hop from one mat to the other without touching the ground. if they get tagged our hit the ground they are out. You then can make them do 5 push ups or whatever you choose. Also if the people that are it touch the ground you can make them do 8 pushups, spin around on their head 3 times. ect. it is a fun game and people get really into it. just make sure that they choose mats that are safe to jump onto that wont slide, ect. you can also use springboards, floor beam, and any other things you find around the gym.
Another game that I played a gymnastics camp doesn't have conditioning directly in it, but it makes you pretty tired. I think the game is called sea or shore?? So you have everybody in the middle of the floor. you make one side the ship and the other the shore. when you yell ship they go to that side shore to the other. they also have other things you do like "climb the crows nest" where you have to prtend you are climbing a ladder, "scrub the deck" get down on your knees and prtend your scrubbing the deck, mates in a dingy where they have to get with 2 other people(only 2 or they are out) and pretend they are rowing a boat, "beached whale" where they have to lay on their stomach and garb their feet and pull up, so it looks like they are a beached whale. if they are the last one to preform the actions or get to the other side they are out. that is when you can make them do conditioning until the gam eis over if you want. there is one more thing. the person that is yelling out the actions is the captain. At any point in the game they can yell captain on deck and they have to stop whatever they are doing a saluet(you know like in the military). then they are not allowed to move until the captain says "at ease"(so like simon says you yell out other actions and if they do them beofre you say at "ease then they are out). When you are getting sown to the end of the game you can yell like ship, shore, scrub the dack, climb the crows nest. and they have to do the last thing that is called. if they are the last person they are out. so it makes you really tired.
ANother one is Fire Water, i think it is called: where you run around the floor and they wait for you to call out either fire, water, landslide,flood,lightning, and hurricane. if you call fire they have to run and go something that is blue(other than the floor), water they have to go touch something that is red, landslide they go jump in the pit, flood they have to get/ hang on something that is above their waist(so they are not touching the ground) lightning they go touch something metal.(ex.the bar poles, beam poles, ect.) and then hurricane they have to go hide under a mat. You count down from 5 after you call out the action and whoever isnt doing the action by the time you get to 0 is out. when you get to the end its just whoever is last. just like the other game you can call out fire, water, lightning and they have to do the last action, if they dont do it they are out. again you can make the people that get out condition.
You can also do contest like stick the most standing tucks, hold the handstand the longest, most pull/ chin ups, fastest rope climb. ect.
Another one i did.(WOW this list is getting long!) was you split them up into even groups and have a hat full of conditioning. each group pulls a piece of paper that say like 15 pushups, 1 rope climb, 45 sec handstand hold, ect. and they have to preform it as fast as they can. when they finish that they come back and get another paper with another conditioning. After they whole group finishes all 5 things of conditioning, they wait for everyone else to finish. the goal is to be the fasted group done. they cannot go onto another conditioning until everyone in their group finishes the conditioning. If they cant do a standing back tuck they can alter it to like a bhs or back tuck on tumble trak.
their is always classic stick it, that doesnt invovle conditioning, pit races, obstacle course with conditioning in it, romeo and juliet(thats what my gym calls. it. when you have a big person and a little person and they do things together like london bridge when one does a bridge while the other goes under it. i can explain if you dont know)
SO SORRY that this post is soooooo long!!

I hope that you understand everything I tried to helps. I hope that these games give you some ideas
