Thinkrolls:
Kings and Queens Review

Thinkrolls: Kings and Queens (2016) is a puzzle game where you roll your character around castles to collect keys, food and gems for the dragon that lives there. Complete a level to be awarded with customising pieces to decorate your ball as a king or queen. The Thinkrolls series is designed to develop children's logical thinking and puzzle solving skills rather than their abilities to press buttons quickly or wield a sword.

There are 18-20 castles to complete in each story, and six stories, varying in difficulty from easy to hard. The easy levels are recommended for preschool age, while the hard levels are for 8-12 year olds.

Difficulty develops slowly and there are no time restrictions or penalties, so you can work out the puzzles at your own pace. Each level has a slightly different set of objects to interact with, and you develop knowledge of the workings of the castle to solve more and more complex spatial puzzles. Drop gears into machines to move barriers, block up holes with falling boxes, activate magical harps to soothe dangerous animals and collect the keys you need to progress.

Thinkrolls is a series of puzzle games for iOS and Android which includes:

• Thinkrolls 1 & 2
• Thinkrolls: Space
• Thinkrolls: Play and Code (which contains 900+ levels plus a level builder to make your own puzzles)
• Thinkrolls: Kings & Queens

Thinkrolls is designed by child psychologists as an educational game to improve children's logical thinking, problem solving, causation reasoning and perseverance. The game is colourful and appealing to younger children, especially the customisation options, while the puzzles are challenging for older children.
