Number Placer Free

免费电话砂矿益智/游戏，生成一个新的难题每次你玩！

Number Placer game designed for ease of use on mobile devices. Simple. Fast. Fun.

This app does not contain any pre-generated puzzles. Each puzzle is generated randomly at the time of play and guaranteed solvable. This means it is extremely unlikely you will ever receive the same puzzle twice!

Three difficulties to choose from:

*Easy - puzzle starts with many places filled in. Great for a quick game.

*Medium - puzzles start with a moderate amount of places set. Normal mode.

*Hard - puzzle starts with a small number of initial values. There may be more than one solution to these, although these puzzles will take longer to solve.

There is also a 'Helper Mode' available. This prevents simple mistakes by only allowing legal plays to be made.

For a quick game: try checking "Helper Mode" then click the "Easy" button. Games played in this mode can usually be solved in minutes!
