Black & White is a colourful grid-based puzzle game created using Pythonista on iOS. This code is intended to be used within the Pythonista app.
Download or clone the repository to Pythonista's file system and run main.py using the Python 3 interpreter.
Pythonista Tools Installer provides an easy way to do this. Black & White is listed in the library under Games.
The config.ini file contains modifiable configuration information. There are currently settings for two size classes in the [LAYOUT_SMALL] and [LAYOUT_LARGE] sections. These may need to be adjused for different screen sizes. You can also customise in-game messages and other aspects of the game.
-
The aim is to score points by clearing a white path across the black and white grid. Tapping a square locks it and toggles the colour of the eight surrounding squares.
-
When the path is cleared, tap the central button at the bottom of the screen. This happens automatically when the timer runs out.
-
If successful, tapping the timer will proceed to the next level. Otherwise, tap it to start a new game. The timer gets quicker with each level!
-
There are three power-ups at the top of the screen. You can get more by collecting stars. They can be very helpful, but not using them may have other advantages! The power-ups effects are as follows:
- Toggle all squares
- Unlock a tapped square
- Toggle a single square (but not its neighbours)
-
Points are awarded for maximising the number of squares in the path, and points are deducted for unused white squares and locked squares (ones you have tapped). Your score in a round may end up negative!
The cog icon in the top left will take you to the settings screen where you can select a difficulty level (which affects timer speed and power-ups), change the username and set a custom colour scheme. For more detailed instructions, you can view the in-game help screen by tapping the ? button on the settings screen.
The high score leaderboard can be viewed by tapping the icon in the top right. There is a separate table for each difficulty setting. Scores are stored for each user name using a local SQLite database.
