【Created by someone who doesn't understand chemistry】 It's okay if you don't understand chemistry or the periodic table! Maybe you can learn while playing? 【Features】 -The rules are the same as that watermelon game. But it's a different playing experience. Because the stage is circular, the elements move all the time. - 4 difficulty levels and 3 game modes. Even for people who are good at games, it is quite difficult to score 5000 points on the highest difficulty level. -You can naturally learn the names of elements while playing. Hydrogen → Helium →……. 【Overview】 "Hydrogen Game" is a puzzle game where you aim to get a high score by dropping 118 types of elements from the periodic table. Players can drop elements. When attached to the same type of element, it changes to the next type of element. If the elements fly out of the circle and hit the wall, the game is over. Elements can be purchased by consuming energy. Use it when it's dangerous. This is a game that uses elements and the periodic table, but even those who don't understand the periodic table can have an explanation during the game, so they can play while understanding the rules. [4 difficulty levels] There are four levels of difficulty: "Easy," "Normal," "Difficult," and "Very Difficult." The higher the difficulty level, the more types of elements will appear. First of all, let's learn the rules of the game with "easy". [3 game modes] Normal mode: You can play with basic rules. Let's start playing with this mode. When you combine elements of the same type, they change into the next type of element. Period + Tribe Mode: This mode has “tribe” rules added to the normal mode. Once you get used to normal mode, try it out. When elements from the same type or family group are combined, they change into the next type of element. Tribe only mode: A mode with only the rules of the tribe. We recommend playing the other two modes before choosing this mode. When you put elements of the same type together, they change to the next element in the same group. 【The goal】 ・Achieve a score of 5000 points. ・Extinguish the 118th element. The game is cleared when you complete the goal in all modes and on all difficulties.
