Guroku is a puzzle game based on a completely new principle that has made it popular all over the world. ▪ The player moves colored stones around the game grid, which determines the directions in which the stone at a given position can move. ▪ The goal is to get the individual stones on the target field of the same color. ▪ Each time a player moves a stone in a selected 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. FEATURES ▪Simple controls - just move the stones in the direction you want. ▪Easy to learn the rules, our tutorial in the introductory levels will help you. ▪Even though the rules are simple, the puzzles in the higher levels will be a challenge to solve. The game is especially suitable for those who like to exercise their brain. ▪Compare your performance with other players on the global leaderboard. If you solve a puzzle with fewer moves, you'll get a higher score. See how others are doing. ▪Collect achievements in the Game Center to add variety to your game experience. ▪The game offers a total of 245 levels of varying difficulty. Try to solve them all. ▪Shake your brain, it's not as easy as it may seem! The game is available exclusively on iOS. Enjoy!

C4K-Coding4Kids is an educational app designed to teach children aged 6 to 12 how to code and develop programming skills. This app provides kids with fundamental and advanced programming knowledge through entertaining activities, games, and hands-on exercises. With nearly 2,000 engaging levels across 22 different games, what does the app have to teach children about basic programming concepts? ● Basic is the simplest gameplay mode of the game, allowing kids to familiarize themselves with the drag-and-drop mechanics of Coding4Kids. In Basic mode, players drag coding blocks directly onto the gameplay screen to help characters reach the end point and complete the game. ● Sequence is the second gameplay mode. From the Sequence mode onwards, children will no longer directly drag coding blocks onto the screen but instead drag them onto a side bar. The Sequence mode introduces kids to this gameplay style and the sequential execution of coding blocks from top to bottom. ● Debugging introduces a new gameplay style where coding blocks are pre-placed but may be redundant or in the wrong order. Players need to fix the order of blocks and remove any unnecessary ones to complete the level. Debugging helps children become familiar with deleting and rearranging coding blocks and understanding how programs run more clearly. ● Loop introduces a new block alongside basic coding blocks, which is the looping block. The looping block allows for the repetition of commands within it a certain number of times, saving the need for multiple individual commands. ● Similar to Loop, Function introduces kids to a new block called the function block. The function block is used to execute a group of blocks placed inside it, saving time in dragging and dropping repetitive blocks and creating more space within the program. ● Coordinate is a new type of game where children learn about two-dimensional space. Coding blocks are transformed into coordinate blocks, and the task is to navigate to the corresponding coordinates to complete the level. ● Advanced is the final and most challenging type of game in which all blocks except coordinate blocks are used. Kids must apply what they have learned in previous modes to complete advanced levels. What will children learn through this game? ● Children learn key coding concepts while playing educational games. ● Help children develop logical thinking. ● Hundreds of challenges spread across different worlds and games. ● Covers basic kids coding and programming concepts such as loops, sequences, actions, conditions, and events. ● No downloadable content. Kids can play all games offline. ● Easy and intuitive scripting, with a kid-friendly interface. ● Games and content for boys and girls, gender neutral, without restrictive stereotypes. Anyone can learn to program and start coding! ● With very little text. Content intended for children ages 6 and up.

Verdict
The clearest difference is price: Guroku at Free against C4K's $2.99. Guroku also leads on rating (4.8 vs 4.0) and ratings volume (48 vs 1). C4K's advantage is in-app purchases (none vs 1) and review sentiment (100% vs 86%). On ads, device support and iOS requirement there is nothing between them.

Guroku is free to download; C4K costs $2.99 up front. Guroku sells 1 one-off in-app purchase. C4K asks for nothing beyond the download.
Guroku holds the better App Store score, 4.8 against 4.0. That said, the two scores are not equally well evidenced: Guroku has 48 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 86% of Guroku's written reviews are positive against 100% of C4K's, so the app with the better star average is not the one people write more warmly about.
