Sigma Sequence play online

Solve math problems in reverse. You are given the solution and are asked to create the problem. Select multiple tiles to add them together, resulting in the correct solution. When the solution is 2, you must select 1+1.

The more problems you solve, the more difficult they become. Red tiles will subtract, and yellow tiles will multiply. The problems will infinitely get more complex. See how far you can go!

Too hard? Try the CASUAL gamemode, with no time limit and infinite lives!
Too easy? Try the BRAINSTORM gamemode, with a 15 second time limit and a 4x4 grid with increased difficulty!
