Four times a year on the equinoxes and solstices, people gather for a game to prove best abilities. There are six abilities and each has a dedicated tribe. Everyone chooses a tribe and represents himself and his tribe. The best half is going to raise the next level. Learn the story of abilities and choose one of: ^ Perception Tribe ^ Integration Tribe ^ Logic Tribe ^ Memory Tribe ^ Motoric Tribe ^ Timesense Tribe *** Rules and tips *** Your goal for the game mission is to reach the top leading corner of the mission screen. The motion of your avatar is directed to the active touch point on the screen. You can freely change the trajectory of motion by changing coordinates of the touch. > What's the challenge? Along the way, there will be a variety of tasks such as mini games and puzzles. Level of difficulty quickly adapts to your abilities, so it's important to think and act flawlessly right. Points are given for each successfully completed task. The number of points increases with the level of difficulty, but the risk of losing also increases. If you lose three times within five tasks, the mission will end, but the points scored so far will be saved. You will have one trial and six set-off attempts to score as many points as possible. The best result will be saved in the overall contest leaderboard. Since the level of difficulty increases in proportion to your abilities and more points are given for successful tasks, the likelihood of achieving a better result increases with each attempt. A new situation and a unique playing field is generated for each mission. This gives you a great chance to improve strategic skills. > What effect does the tribe have? You are more likely to encounter tasks that are more suited to the strengths of your chosen tribe. > Can I change tribe? Yes. Once after the end of any of the game seasons, which are held in spring, summer, autumn and winter. > Win conditions? At least you need to go to the next level. The best half of participants are going to raise the next level and are waiting for new tasks and new discoveries in the new season! Also all contest games will be available in the 'Game of the Day' Helius' collection for summary and waiting time between seasons. Otherwise, it is possible to try in the next game session. The session continues for one month and your personal result will be changed by other achievements. It's like the Olympics ;) > Seasons The Helius' World games will be held annually, for a month in spring, summer, autumn and winter. Good luck with the Helius' world games! *** The app based on a contest mode and requires connection to the Apple Game Center with dedicated recurring leaderboard.
