The Beta version is live on Patch 8.16 on all servers to be tested for a potential permanent game mode besides Summoner’s Rift and Aram.

About the game:

The game in a full new small map has now Two jungler from a 5 players team, the other 3 laners share the two lanes so close to each other only separated by thin bushes. The junglers can now share buffs, XP and gold when in the same range of the monsters they kill. The small map with too many bushes made it easy for the junglers to clear fast and have more time to gank both lanes and participate in the events.

The events (Rewards):

Before each event, A 30 second countdown timer will appear on the screen for teams to get ready for a random spawn of the event. Winning the event will get the whole team a strong temporary buff.

Push the Cart: A cart with a range circle appears in the middle of the map, whatever team has the most players inside the circle will push the cart to the other end to blow up an objective (turret, inhibitor …). This event is time bound and the cart will turn into Mecha Zero Sion train al destroys an objective.
Bardle Royale: A wide flaming circle will appear on the map same as in games like Fortnite, it will get tight rapidly. Any champion outside the range will have a quickly loss of health to death and you can’t respawn until the event is done. The team that has at least a champion alive inside the circle will win and receives a buff.
Loot Teemo: A Devil Teemo will appear on the map, attacking him will give gold and last hitting him will give the team a buff.
Snowball Fight: Your both spells will be changed into a snowball spell like in Aram but with no damage and short cooldown of 2 or 3 seconds. Hitting an enemy will get him slow. The team with most hits will win the even and receives the buff.
King of the Hill: Another circle will appear on the map with charging points serve as a timer, kill the other opponents and stand inside of it to win.
Sudden Death: This game mode will not have an open time as other game mode. Both teams nexus will get up in a shape of a big minions and start walking to the middle of the map. Protect your nexus while hitting the enemy nexus to destroy it and win the game.

Tips and Tricks

Poppy and Fiddlesticks are OP Champions in this mode since both have ultimates that will help the team to get the events easily. Poppy will throw the enemy team out of the range of the event whereas Fiddlesticks will ult them inside a small surface then use a Stopwatch or Zhonyas. Be wise where and when to use them.
Most of the old Items are back into the game, try to form a good combo for damage and resistance.
When receiving Buffs out of events, take the opportunity to get objectives before they are gone.
Gather in the middle of the map after the timer of the event appears on the screen. This will help your team to set ambushes for any lonely enemy champion coming.
Use the three wards given, be wise where to put them and most likely they will win you the game.
Junglers shares everything in the jungler and Laners too. When you see a Jungler doing buffs on his own, feel free to participate and share.
If you are on a killing spree and not dying, you will be on fire, all stats will increase. Protect the one on fire in your team to get more damage to the enemy team, killing him will give loads of gold.
Many champions are Op in this game like Zyra, Trundle, and I guess Caitlyn is the most OP because of her w, since there are many bushes to put them in, that will give her range and damage.

Please let us know other Tips and Tricks and the most OP champions you tried in this mode. Thanks in advance.
