Q. Some players use the “tap method” to move the blocks out of place while players like the “slow slide and pull” trick. Which do you suggest?
A. I use both techniques, depending on the circumstances. I also resort to the ‘squeeze and shift’ move when things get desperate. If the central block has been removed from a layer, it is possible to squeeze the remaining two outer blocks together, thus shifting the tower so that the layers above are now balancing on just one of the blocks, leaving one block free to remove. (Hard to explain, easier to demonstrate)
