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 zero's 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. Sign in to Google Play services to measure your speed against other players.
Hint: Longer answers give a lot more points and time!
Zen:
Play endlessly, without pressure from a timer or goals. 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!
