Leaners in a Line
It is possible, though difficult, to stand discs on other standing discs. It is advisable to practice this technique without other magnets nearby. Note that in a game it is unlikely that an opponent will let you exploit this technique fully, and you might be limited to a small leaner chain.
Try to lay the first standing disc as low as possible. Bring the next disc along the mat carefully and slowly slide this disc towards the leaner until the leaner starts to wobble due to the disc you are moving. If the first leaner falls flat to the ground, then you probably placed it too far from the foundation disc. Slowly increase the angle of the third disc; the more vertical you make the third disc, the more vertical the second disc (the first leaner) will tend to become. And the more vertical the second and third discs are, the more their attraction will be to each other. Therefore, be sure to stop increasing the angle of the third disc as soon as you see the angle of the second disc increase. Slide the third disc back and at the same time lift it up some more: This is a tricky step: At the same time, you want to both barely tilt the third disc and barely move it away. Increasing the angle of the third disc increases the attraction it has to the second disc (preventing it from falling flat), while moving it away prevents the leaner discs from snapping together. It is important to note, however, that the movements in this step are very small. Any movement more than a millimeter is too large. Gently let go of the third disc. If everything goes according to plan, you should be able to let go of the third disc and have a double-leaner! Further leaners can be placed against these ones following the same method.
If the leaner in the front gets too low, it will fall, and so will every other standing disc. This can be a good way to get a line of foundations quickly.
These leaner lines are very unstable and can be good for offence.
Rolling Standing Pieces
You can roll standing pieces around their foundation using the forces of the action disc. This can be tricky because the standing disc will tend to get closer or farther from the foundation as it moves. If it gets too close it will snap together (bad). If it gets too far away it will fall down (not as bad).
Hold the standing disc roughly between horizontal and the andle of the leaner, opposite the side you wish the leaner to roll. Push from the inside (over the foundation) if the standing piece has a high angle to help push it away from the foundation. Push from the outside if the standing disc has a very low angle so it doesn't fall down. This is more risky because it might stap to the foundation. You may have to alternate between pushing inside and outside as the angle changes.
You can use this to try and adjust the angle of an already standing piece. If you have a high leaner that you want to convert, you may be able to lower the angle first by pushing it around from the inside.
