Sigma Sums is a simple tile-based number game that is fun and challenging for all ages.Test your speed and climb the leaderboards in Timed mode, play endlessly in the laid-back Zen mode, or try to solve the entire grid in the Puzzle mode.**************How To Play Video: https://www.youtube.com/watch?v=C7zR2QhDuLw&t**************Detailed How To Play:General:Given a sign (+ − × ÷) find an appropriate sequence of adjacent tiles such that the sign can be placed somewhere in the sequence and an equal sign (=) somewhere after it such that the equation it creates is correct.e.g. for the sign + the tiles 3->1->4 are correct because 3+1=4.e.g. for the sign × the tiles 3->7->2->1 are correct because 3×7=21.e.g. for the sign - the tiles 1->2->3 are incorrect because 1-2≠3.Hint: leading zeros can be used, so e.g. with the sign + the tiles 1->7->0->5->2->2 are recognized as 17+5=22.Timed:Play as long as you can, each correct answer grants you score and a (small) time increment.

Switch to only having the + - signs in the settings for an easier experience.Puzzle: Completely clear the board given a predetermined pool of signs with corresponding answer lengths. Each dark sign is the start of a correct answer of the solution that the game has envisioned. Other solutions might be possible!
