App Description

Welcome to 'Grid Hero', a collection of number games.
Currently includes games: Hitori, Sudoku, Kuromasu, FindNine, Skycrapers, SlitherLink, and Oneness.
All games have leaderboards on GameCenter.
Continuously adding new games.

Hitori:
Hitori is a unique puzzle game where the goal is to eliminate adjacent repeated numbers. In each board, you need to follow these three rules:
Uniqueness Rule: No row or column can contain the same number. In other words, identical numbers cannot be adjacent in each row or column.
Black Block Rule: Some cells are initially marked as black blocks. Numbers in black blocks cannot be adjacent.
Isolation Rule: There should not be two adjacent white blocks. No white block can be surrounded by other white blocks, forming an isolated area.

New Added Sudoku Features:
Multiple Difficulty Levels: Sudoku comes in four levels - Easy, Normal, Hard, and Master, allowing you to choose a challenge that suits your skill level.
Pencil Mode: Enjoy the convenience of Pencil Mode to mark candidate numbers, improving puzzle-solving efficiency.
Undo/Redo: Experience a relaxing puzzle-solving experience with the ability to undo and redo actions, correcting mistakes at any time.
Auto-fill Candidates: Speed up the puzzle-solving process by automatically filling in all candidate numbers with just one click.
Candidate Lock (Long Press to Lock): Easily fill in consecutive numbers by tapping and holding to lock the candidate number.
Eraser Lock (Long Press to Lock): Consecutively erase cells with a long press to lock the eraser function.

Newly Added Nine Find:
Circle each number from 1 to 9, and ensure that the sum in each row and column is not greater than 9.

Newly Added Oneness:
Turn all numbers into 1!

Newly Added Kuromasu:
Paint the grid black according to the following conditions:
1. Each number on the board represents the number of white cells that can be seen from that cell, including itself. A cell can be seen from another cell if both cells are within the same row or column, and there are no black cells between them in that row or column.
2. Numbered cells must not be black.
3. No two black cells must be horizontally or vertically adjacent.
4. All the white cells must be connected horizontally or vertically.

Newly Added Slitherlink:
The objective of the game is to connect the dots with line segments to form an unbroken and non-crossing loop:
1. The number of line segments around each number must be equal to that number.
2. In areas without numbers, there is no restriction on the number of line segments.
3. Line segments can form a continuous loop and must not intersect or branch.

Newly Added Skycrapers rules:
The objective is to place skyscrapers in all cells on the grid according to the rules:
1. The height of the skyscrapers is from 1 to the size of the grid i.e. 1 to 4 for a 4x4 puzzle.
2. You cannot have two skyscrapers with the same height on the same row or column.
3. The numbers on the sides of the grid indicate how many skyscrapers would you see if you look in the direction of the arrow.
