Hexagon Invader is a simple tap-tap game for everyone and good for keeping capability in rapid-reaction. - Four game difficulties for any kind of players - Support color mode(GREEN/YELLOW/RED/WHITE) and gray mode (colors marked as '2', '1', 'o', WHITE) Initial map has 61 hexagons, one is GREEN(or marked '2'), others are WHITE (no mark). Player only need to tap on those GREEN(2)/YELLOW(1)/RED(o) hexagons. While playing the game, the color of hexagons will keep changing randomly as time goes by. Player must be very concentrated and tap quickly to win the game. The rules: 1. Tap on GREEN, the hexagon changed to YELLOW. 2. Tap on YELLOW, the hexagon changed to RED, meanwhile the neighbors(WHITE) of the YELLOW changed to GREEN simultaneously. *This is the only way to change WHITE to GREEN.* The GREEN/YELLOW/RED hexagon will change back to WHITE/GREEN/YELLOW automatically and randomly. 3. Four difficulties: easy: game time is 90 seconds, one hexagon changed back per second medium: game time is 180 seconds, two hexagons changed back per second hard: game time is 270 seconds, three hexagons changed back per second impossible: game time is 360 seconds, four hexagons changed back per second 3.

Puzzle helps to learn Cartesian coordinate system (x,y) and practice to calculate sums over the line (the very first step to understanding integration). Sound: switch Ring/Silent controls speaker. After 30 seconds quick shake to restart the puzzle or reveal the answer with just a tap. In Gradients puzzle each cell has a value that contributes to the sum when calculated along a row or a column. Additionally, the value of each cell depends on the direction of the summation ("anisotropic field"). Sometimes, the clues can be satisfied by different pattern of orange cells. This means that, without additional information, solving the puzzle may involve a guessing step. An interesting phenomenon is the formation of "isomers", where an alternative solutions can be created by inverting a subset of cells. When playing for fun, any of the isomers is considered a valid solution. However in Competition mode, one more clue is added: a sum along the main diagonal. This additional clue helps distinguish between isomers.
