The Pendulum & the gatekeeper

Pendulum
groups of 3, 2 blockers and 1 jammer
blockers should be in a wall. Jammer should try to go in both directions around them. When the jammer goes in, the inside blocker will stay in front and the outside blocker will be at her side. When she goes out, the outside blocker will be in front and the inside blocker will hit from the side. Back and forth like a pendulum! Blockers should be touching each other as much as possible without multi-player blocking. The outside wall blocker will always hit to the inside and the inside wall blocker will only hit to the outside. The line can be a 3rd blocker, as jammer will have to go back and around to get out of a box on the line.

Gatekeeper
4 lines, 3 blockers, 1 jammer. 3rd blocker is the designated gatekeeper.
2 blockers form wall, 3rd gatekeeper blocker use that wall to control the jammer and set and spike jammer. The 2 wall blockers should stay close together and not try to hit the jammer - only the gatekeeper can swing! The 3rd gatekeeper blocker, will use the wall to box in the jammer. She should be touching the wall blockers as much as she can without multi-player blocking. Wall can try to lure the jammer to inside with positioning and close the door.

Double Gatekeeper
4 lines, 3 blockers, 1 jammer. The middle blocker is your post and the inside and outside blockers are your gatekeepers.
If the jammer is going to the inside of the track, the inside gatekeeper and post blocker form a wall, stay close and not try to hit the jammer. The outside gatekeeper would then swing/drop back and close the gate on the jammer. This also applies to the outside. If the jammer is going to the outside of the track, the outside gatekeeper and post blocker form a close wall and not hit the jammer. The inside gatekeeper would then swing/drop back and close the gate on the jammer. The middle blocker will also be the post and does not engage the jammer at all...they are there to form that solid wall of two. The gatekeepers must ensure that only one gatekeeper is closing the gate at one time and that they are touching the wall blockers as much as they can when closing the gate, without multi-player blocking.
