TurtleFlip & Adiro: alienated peg jump

25 January 2009

turtleflip.pngWith this post, I will finally finish off the sequential removal puzzles, as far as I have found them in the app store (see all posts in this category). In a sequential removal puzzle, objects have to be removed according to some rules. By taking the wrong order of actions, you might end up in a dead end, so sequential removal puzzles can be seen as an abstract kind of maze (see my earlier primer on maze puzzles explaining this in more depth).  

In real-life physical puzzles, sequential removal puzzles are not so widespread, because it is difficult to find interesting rules for removal that are transparently executable while manipulating objects on a board. Peg jump is possibly the only physical sequential removal puzzle. In contrast, for computer games the principle of sequential removal is very widespread, because even rather unwieldily rules of removal can be easily implemented for a computer to consistently perform. No cheating or accidental errors can occur. Because the goal of removing things, viz. clearing the board, is so intuitively simple, many computer games use this principle (just look at the dozens of Bejeweled-like games in the app store). The differentiation between such games lies in the details of the rules of removal. Enter the twisted rules of TurtleFlip!


FLIP: nice try, but not yet ready

22 January 2009

IMG_0001.PNG The app FLIP is a combination of a Bejeweled-like match-three game, a tilt maze and a match-and-vanish puzzle. So in principle, there are many very interesting puzzle concepts combined into one neat little package. However, the execution leaves much to be desired, and the level-design is not very challenging. So, I really cannot recommend this app just now, but I will keep an eye on any updates.


Match-and-vanish puzzles with limited moves

15 January 2009

IMG_0001.PNGThe match-and-vanish principle of sequential removal puzzles has taken off in the numerous Bejeweled variants, also en masse found in the app store. As a side-effect, as few of such arcade games have developed separate puzzle modes alike to Vexed. Different from Vexed, these puzzles all take the Bejeweled cue that you have to get three identical tiles together before they disappear (in Vexed also groups of two tiles disappear). Also different from Vexed is that these puzzles do not have any walls that block the movement of the blocks. The only constraint are blocks of other color that are in the way. This does not allow for difficult puzzles, so all these puzzles have to add an extra constraint, and that is that the number of allowed moves is limited. So, these puzzles are not so much about removing all blocks (which is easy), but to do so within a pre-set number of movements (which can become pretty difficult).


Vexed: the original match-and-vanish puzzle

14 January 2009

vexed.pngContinuing the series about sequential removal puzzles, this post introduces Vexed, which is probably the first puzzle to use the principle of automatic and immediate removal of tiles when identical tiles come into contact. This principle has become enormously popular in the wake of Bejeweled and its masses of clones and variants. Bejeweled turns this principle into an arcade-style game because removed tiles are replaced by new ones. Vexed has a clearer puzzle logic: remove all movable objects by bringing identical objects together.
