Grid Games

The Grid Games app contains four accessible puzzle games: Sudoku, Pairs, Squares, and Leaf Sweeper.

The size and style of the numbers shown in the Grid Games puzzle games change as the Android Accessibility Font Size and High Contrast Fonts settings are changed. The Pairs and Squares games also have their own zoom settings to make all the squares bigger. If the grid in any game is too large for the screen, it can be scrolled to bring the squares of interest into view.

The games also respect your choice of Android Light and Dark colour modes.

The TalkBack screen reader announces the contents of the grid squares in the games, and their position in the grids. TalkBack also announces changes to the squares as the games are played.

The Sudoku game shows a grid of 9-by-9 squares. To win the game, enter a number from 1 to 9 in each of the blank squares show in the grid, such that each row and each column in the game contains the numbers 1 to 9. In addition, the grid is divided into nine 3-by-3 groups, with group 1 containing the nine squares at the top left of the grid, and group 9 containing the nine squares at the bottom right of the grid. Each group must contain the numbers 1 to 9.

The Pairs Game is based on a traditional card matching game, where face-down cards are turned over to find pairs of cards. When the game is run, a 4-by-4 grid of blank squares appears, with each square representing a face-down card. When one of the cards is turned up, it reveals an image on the face-up card. When another card is turned up, an image is also shown on that second face-up card. If the two images are the same, then the cards are matched and will not change again for the rest of the game. If the images do not match, then the cards are unmatched and the cards must be then turned back down. These steps are then repeated until all matching images have been found.

To have your own pictures shown in the Pairs game, along with custom accessible names and descriptions, please follow the steps described in the Pairs Settings page.

The Squares Game is based on a square sliding puzzle, where squares in a grid of squares are rearranged by the player to form an ordered sequence of squares in the grid. When the game is run, a 4-by-4 grid of squares appears, with fifteen of those squares occupied with a movable element, and one square being empty. When a square is clicked, if it is adjacent to the empty square, the clicked square moves into the empty square. The space where the tapped square was then becomes the empty square. The aim is to arrange all the squares in a sorted order, leaving the empty square in the bottom right corner of the grid.

The Leaf Sweeper Game is based on the traditional Minesweeper game, but the aim of this game is to sweep the leaves off a group of paving stones without disturbing frogs resting under the leaves on the stones.

When the game is run, a 4-by-4 grid of squares appears, with each square showing a leaf symbol. First clear the leaves off one of the stones by clicking on the stone. When the leaves are cleared, the number of frogs in the stones adjacent to that stone will be shown on the stone. If no frogs are on adjacent stones, then the clicked stone shows nothing. In addition, all adjacent stones with no frogs will also be cleared until blocked by stones with one or more stones showing nearby frog counts.

When you feel you know that a stone must have a frog resting beneath its leaf, mark it as "Query Frog" by clicking the stone and selecting "Change Query Frog state".

Once all paving stones in the grid which don't have resting frogs on them have been cleared, you've won the game.
