Ophex

Seven numbers sit in a hexagonal layout and must all be merged into a single target value. Tapping an operator between two adjacent numbers combines them with addition, subtraction, multiplication or division; fractions and negatives may appear along the way, though the target is always a whole number. Undo, redo and streak tracking are built in.
