Boolean numberline - Range invaders

Description: Range invaders, is a game that teaches boolean algebra using an integer numberline and integer intervals. Every interval in the game is randomly generated and increases in difficulty as the user completes each level. The goal of the game is to save your livestock by blocking alien abduction rays with dynamite. Dynamite is placed based on the player's solution; using a numberline at the bottom of the screen. Players click integers on the numberline to specify the range they wish submit as their solution. Each level has three stages and the player must be at least 70% correct to continue to the next level. Points are awarded to the player when the level is complete. The player scores more based on how many livestock they saved by the end of the level. Additional points are awarded for getting the solution 100% correct. Early levels in the game focus on single ranges while later levels introduce multiple ranges.
