Reach 100 : Colors Game

Reach 100 : Colors Game is a sliding sum puzzle. Each level holds a set of shapes carrying numbers, and you combine them until they add up to exactly 100.

Shapes move in straight lines, horizontally or vertically. Push one into another and their numbers are added together. When a shape reaches a total of 100 it freezes: from then on it cannot be moved or used again. A level is finished once every shape has been grouped into a sum of 100.

So every level is a question of partition. Which of the numbers on the board belong together in a group that totals 100, and in what order should they be joined? There are sixty levels, and the developer says they become more complex as you progress through them.

Drag a shape horizontally or vertically to slide it into another. The two numbers are added together. Keep combining until a shape shows exactly 100, at which point it freezes and can no longer be moved or used. When every shape on the board has become part of a 100, the level is complete and you go on to the next.

Before moving anything, add up the numbers on the board and look for groups that make 100 together. Since a completed 100 freezes, finish the groups you are sure of and leave uncertain pieces free until you know where they belong. Shapes only travel horizontally or vertically, so plan which direction each one needs to go.

A number puzzle about grouping values into sums of exactly 100, played in a portrait frame. There are sixty levels. Shapes are moved by dragging them horizontally or vertically, and completed hundreds freeze in place.

Math Box Balance is also about totals, swapping number blocks between boxes until every box sums the same. Number Arrange asks you to swap numbered boxes into order on grids as large as 7x7.
