Wedge Math Puzzle - Brain Exer

Our game is a puzzle of numbers and operators you need to arrange into valid equations by selecting and dragging tiles to empty places at the board, with cool motion, 5 game modes, customizable difficulty, thousands of levels, and an appealing visual package with pleasant music.
There are 5 game modes that users can play, starting from a single line equation, and going up to 5 lines of equations. Each equation is pretty simple, for example, 0+1=1. We use multiplication, addition, and subtraction, with numbers in the range 0 to 999. Each number and operator of the equation appears on a different tile. The board is arranged at the start, some of the tiles become "wedges", that the player can not move, they are usually marked with orange color. Movable tiles are placed below the board or inside the board. The player needs to move the movable tiles until all numbers and operators are placed inside the board, and each line is a valid equation.
Recently we added four dynamic backgrounds to enhance the visual appeal of the game and convey a relaxing feeling to the player, with natural landscapes.
The player can use a difficulty slider to adjust the complexity of the puzzle from easy to normal, and even hard. Difficulty slider provides a highly customizable and individual challenge for each player. The player can start with easy difficulty and progress at their own pace to harder difficulties. The differences between the difficulties defined by randomized shuffling function. As a general rule, the bigger the board, the more complex it is to solve.
While playing, the game shows exactly how many tiles the user moved and how long they are playing at the top of the screen.
The game comes with 6 music tracks, playing in the background but can be stopped, skipped, and volume can be adjusted.
Sound effects can be adjusted or muted.
The game allows for the user to set reminders for each day when to play. Each day reminder can be adjusted by the player. In the "Settings" screen, a day can be turned off by pressing on the day, and all reminders can be completely turned off by a single press on the "Reminders" button.
