Tumbler Puzzle Completing the Last 2 Rows

Ok, you are nearly there. At this stage you have the benefit of a choice of two moves as shown below:

Move Sequence 2 Move Sequence 3

These two moves are completely different and, therefore, give you plenty of options. As you start to complete some columns the swap in column E of the first move will not upset a completed column (although the two barrel sections may be shifted deliberately to achieve the required effect.

It is important to start by studying the current state of the puzzle. You will probably find that some of the beads in rows 3 and 4 are already conveniently placed. Choose from the two moves above one that gives a benefit of one or two (or even three!) correctly positioned beads.

Once again ensure that the barrels is correctly positioned use the 'pegs' as guidance for which beads are being affected.

Left Hand Side:

R LL LL D UL UL R LR LR D UR UR

Right Hand Side:

R LL D UL UL R LL D UR R LR LR D UR
Continue to use these two sequences to complete the whole puzzle as shown on the right.

With practice you should be able to remember the move sequences. You should also find that it takes you fewer numbers of move sequences as you are able to be more adventurous and shift the barrels to place more beads.

Finally, study the 'Notes for advanced users' to get more tips on altering the moves to increase your options.

Once again, more flexibility can be obtained by doing the reverse of the sequences to move the beads in the opposite direction to the arrows in the figures at the top of this page. Also, the mirror image of these move (i.e. Rotating Left instead of Right and visa-versa) could be performed to give you greater diversity.
