I share under the common denominator of 'sequential movement' puzzles, all puzzles that require some moves to be taken many times. They come in many varieties, but I don't have many subsections here. The creator of many of these (many good ones, that is) is 'Thinkfun', whom I devote an own section too.

Lunar Lockout
was the first puzzle of this kind I have and still is one of my favourites. It was originally designed by Hiroshi Yamamoto and Goro Tanaka, Mine Uematsu (the NOBrain Corps), along with Harry Nelson, developed the rich set of challenges for Lunar Lockout. The idea is to move your own 'man' to the middle of the docking station, by moving horizontally or vertically. Whenever another robot is hit you stop. You are allowed to move any robot on the board.

In Pete's Pike the rules are identical to Lunar Lockout. This time it is Pete who, helped by his goats, needs to get to the top of the mountain, which is the middle of the board. It is slightly bigger than Lunar Lockout and more attention is paid to the design of the game. It being my second of the same kind made it slightly less exciting for me.

again is a noce and compact box, consisting of only frogs. They can jump in six directions. The rules for removing the forgs are like Solitaire: once you jump over one, it is removed. The goal is to finish with the red frog on its own in the very center of the board.

Rush hour
is really one of the classics in its kind. Moving your own little red car through all other cars in the jam, in levels ranging from extremely easy to very challenging. I have the 'deluxe edition', which is slightly more elegenat than the normal plastic one (the cars are chrome) and 1 extra pack of challenges (of which there exist 5 I think).

Some of these really are classics, they are sometimes sold by Thinkfun as well, but they just deserve an own section.

The fifteen puzzle
is the classic one with 15 little squares, on a 4x4 grid. The idea is to either get the order right, or take one of the many other challenges possible with this puzzle. Can anyone tell me why it is not possible to either (1) interchange number 14 and 15, (2) put all the piece in reversed order or (3) interchange any two subsequent numbers?

is pretty similar in idea to many of the Thinkfun puzzles above. There are several levels in the metro networks of severalcities. Stations are indicated and the different pieces of trail can be rotated in order to make the route indicated in the assignment possible.
