Guroku Rainbow is the successor to the popular Guroku game, which is expanded with new types of stones, bringing even more gameplay possibilities and even more interesting puzzles to solve.

The player moves colored stones around the game grid, which determines the directions in which a stone can move at a given position. His goal is to get the individual stones to the target square of the same color. Each time the player moves a stone in a chosen direction, that stone does not stop moving until it hits another stone or arrives at a position on the game grid from which it is no longer allowed to move in that direction. This principle forces players to devise clever solutions, such as strategically placing other stones in such places that the moving stone stops where it is needed.

This unique game mechanic, which won the original Guroku so many fans around the world with its originality, is expanded in the new Guroku Rainbow with two new types of stones.

The rainbow stone (from which the game gets its name) can be placed on a target field of any colour. And because in Guroku the stone can no longer move once placed on the target square, the player must keep in mind when strategizing for a particular puzzle that the stone may accidentally stop in the wrong place. And frankly, some puzzles are deliberately designed so that the player must try to avoid such a mistake.

The white stone, which is the second new feature that Guroku Rainbow brings, also doesn't have a target field of its color in the game grid. In fact, its property is that the first time it hits a regular stone of a base color, it takes the color from that stone and it stays that color. The player must therefore search for a solution to the puzzle that will allow him to recolour the white stone to the required colour at the right moment.

Both of these innovations have allowed us to prepare 110 new puzzles that come with the game. And we'll be adding more as part of each update - as with the original Guroku, which now has 235 puzzles.

This is a high quality puzzle game. Very tough, it will get you thinking in creative ways very quickly. The puzzles are all unique and very thoughtfully designed.

[My only niggle is the lack of an undo button. Some of the solutions are really long and must be restarted if you make a mistake. I hope an undo feature can be incorporated, so the player can experiment and play around with strategies.]

Developer Response ,

Thank you very much for your feedback. During the development of the game, we considered incorporating an Undo button. But we decided not to do that, because some levels are designed in such a way that there is a catch, where the user has to think several moves ahead what the consequences of his moves will be. A back button would allow the trial-and-error method to progress to some extent, and such levels would lose their charm. But you're right that in other levels the button would make sense, perhaps to correct a move the player made by mistake. We will try to think about it some more - maybe the button could be available only in some levels, or maybe only for one move back... Hopefully we can find the right way to add that button to the game without it having negative consequences.

Ads ruin the game

Interrupted by an ad in the middle of one of the longer levels and broke my focus and then the app crashed and I lost all my progress. I wanted a nice easy game to relax to, not get jump-scared by a wordscapes ad.

A great sequel to Guroku

I truly enjoy this game. It’s Guroku with a twist. If you enjoy playing Guroku you will love this game as well. I’m looking forward to more puzzles in future updates.
