Description
'The TETRING' is a puzzle game designed and developed by the Korean game developer, Seongjin Kim.
'The TETRING' is a new attempt to demonstrate the four-color theorem of mathematics using color blocks and to combine academic results with games.
Whether the color is sufficient to color all the countries on the map to avoid duplication of neighboring countries was first known in 1852 and is a mathematical difficulty that has not been resolved over 100 years. Many mathematicians, scientists, and the general public at the time attempted to prove it, but proving the five-color theorem was a difficult mathematical task until the end of 1800. The evidence for this difficulty is four-color theorem, four-color theorem-color problem, have.
Later, the four-color theorem was demonstrated using computers in 1976, the first evidence of the use of computers. Perhaps the proof of the mathematical proof of the computer would be the first artificial intelligence revolution to announce the beginning of the AI period.
'If you live in that age, do not you think you can prove a four-color theorem?' Or do you think, "Can you prove it better?" Try it once. Maybe you can better prove the four-color theorem or you can find the opposite of the four-color theorem.
Please specify the color of the map so that colors do not overlap. If you have only paper and a pen, you can try it. If you do not have paper and pen, the other way is 'The TETRING'. It is a unique puzzle game that no one has tried yet.
'The TETRING' is a very simple puzzle game, but it is based on a very difficult mathematical proofreading. No one will be surprised at how you have not tried.
Have you ever had the pleasure of solving difficult problems? ^^ Challenge 'The TETRING' and the four-color theorem ...
How to play: ★ Swipe the block up, down, left, and right. ★ Swipe All blocks move together in one direction. ★ The same color block on the same movement line is removed. ★ Every time you move, a random color block appears at random position. ★ There is no time limit, but there is a limit to the number of passengers.
Game Features: ★ It was difficult mathematics to use 4 color theorem. ★ Provides a picture of a fun brain map by analyzing the number of color blocks removed. ★ The matrix size of the game is 3X3 to 16X16. ★ Play for free and enjoy the game without Wi-Fi connection! Easy mode for all ages, NORMAL mode ★ Hard mode, Ultra mode and Hidden mode for puzzle enthusiasts ★ Color mode [Dyteranopia, Proteanopia, Tritanopia] Option ★ Night mode on / off function. ★ Language support in 20 countries. ★ Leaderboard (ranking system) support. ★ Achievement mode support: Provides achievement system according to the number of patterns of four colors. ★ There are interesting background sounds and sound effects.
