The game consists in receiving 20 random numbers between 1 and 999 and inserting them in a list in ascending order. At the start of the game, you will be presented with the first random number between 1 and 999. You will have to enter it in the empty list at the position you want. Subsequently, you will be presented with the other numbers one at a time and you must place them in the list in the correct place so that the list remains sorted in ascending order. For example, if the first number is 150 and the second number is 80, you would insert the second number before the first in the list, thus obtaining the sorted sequence: 80, 150. You will need to continue entering numbers into the list in ascending order. With each new number that is presented to you, you will have to evaluate its correct position in the list based on the numbers already present. You can compare the new number to the items in the list one at a time, starting from the beginning or the end, until you find the point where the new number fits correctly. The game requires attention and a good sense of numerical order. You'll need to make quick and accurate decisions to correctly place the numbers in the list as they are presented. The goal is to complete entering the 20 numbers in the list so that they are sorted in ascending order. This game is a chance to test your sorting skills and ability to think logically. You can challenge yourself by trying to complete the game in the shortest time or compete with other people to see who can get the numbers right the fastest.

In Roll, you have 2500 rolls to collect as many points as possible. Roll your dice to gain points, spend your points to upgrade your dice, and repeat. Borrowing gameplay elements from strategy, clicker, and roguelike deckbuilder genres, Roll creates a perfect balance of relaxation with critical thinking. While the "Clicker"/"Incremental" genre is not known for its variety or depth of game mechanics, Roll offers a unique dicebuilding system which allows you to explore different strategies and synergies between upgrades. Each run will present you with new and interesting decisions creating a huge depth of strategy and keeping the game feeling always fresh. Roll is designed to be a relaxing and meditative experience. Get lost in the satisfying sounds and effects as all your worries melt away. From the minimalistic UI to the slow peaceful music, everything was designed to create the perfect zen environment. If you enjoy building an engine and watching it grow, chasing down highscores, or just need to escape from your own thoughts, then I really hope you'll enjoy my game, Roll. :)
