# Tristis 1.0 for iOS - Cosmic, Magic Squares, Logic Game with 4 Levels

January 16, 2012 in Games (E)

[prMac.com] St. Petersburg, Russian Federation - Coil Devs today introduces Tristis 1.0 for iOS, their new cosmic, magic squares, logic game with four levels of play and more than 300,000 puzzles. Set against a background containing a rotating spiral galaxy amidst a twinkling starfield, players must solve 5x5 magic squares, where the sum of each row, column, or major diagonal equals 65. Purple tiles from 1 to 25 are dragged from the right to the left square and can be moved to any empty square at any time during gameplay. Purple number tiles can also be returned to the right square and stored until needed. At the start of play, the left square already contains some grey tiles, which are immovable because they are already in the correct position to solve the current magic square. Sums are automatically displayed along the top and left margins, immediately reflecting changes as users move tiles.

A popular puzzle in recreational mathematics for thousands of years, most magic squares seen in newspapers and magazines are of the simpler 3x3 or 4x4 variety. All the magic squares in Tristis are five cells wide and five cells high, with a total of 25 cells. Only one chip or tile can occupy a cell, and cells with grey tiles cannot be changed. All 5x5 magic squares have "65" as their magic number, and the five cells in every column always add up to 65, as do the five cells in every row, as well as the five cells in both major diagonals.

All 25 chips in each puzzle occur only once, so each completed magic square contains all the integers from 1 - 25 in one of hundreds of thousands possible arrangements. The game feature instantaneous computation of the sum of every column, row, and diagonal, which allows the player to focus their attention on the logical steps in solving the puzzle, rather than spending most of gameplay adding unwieldy groups of five integers. As soon as a new purple chip is moved into place, all sums are updated, and similarly if a chip is moved or removed.

The animated spiral galaxy and futuristic music contribute to the feeling of playing a game based on the pure logic that is responsible for all the physical and mathematical laws of the universe. Expressed by the ancient Greek philosopher, Pythagoras, as The Music of the Spheres, the mathematical nature of the laws governing the universe was recognized in many ancient cultures around the world. Dragging purple tiles create animated motion trails, changes to the gameboard that result in sums greater than 65 are highlighted in red, or green for a perfect 65, and a digital timer tracks the amount of time necessary to solve the puzzle.

Feature Highlights:
* Magic squares played in outer space
* Add chips to 5x5 grid so that the sum of all columns, squares, and diagonals equals 65
* Four different levels of play
* Ask for a hint at any time
* Take back moves at any time
* A game of pure logic, where each puzzle has a unique solution

There are four levels of play in Tristis, including: Beginner (14 grey tiles in place at the start of the puzzle), Easy (13 grey tiles in place), Medium (12 grey tiles in place), and Hard (11 grey tiles in place). New puzzles are generated according to a formula at each level, and only at the Beginner level is the player guaranteed a "giveaway," a row, column, or diagonal of four grey tiles that needs just one purple tile to reach 65. Players can ask for a hint at any time, and the game includes Game Center integration. Certain to teach and challenge logicians and gamers at every level of expertise, Tristis provides a new puzzle every time.
