Let’s have a look at the Avokkido creations:

We ARGH Pirates

We ARGH Pirates is a pirate adventure puzzle game designed for children between 6 and 8 years old and highly enjoyable by adults as well – I can tell you that for sure. The game has 4 main characters with hilarious personalities that will help you find all the treasures and solve the puzzles.

The funky pirate crew of 4 is composed of Captain Rose, Claire ‘Long Hair’, Ruprecht ‘The Shovel’, and Zany Granny.

The game graphics and sound are amazing and I can tell that a lot of work has been put in drawing all the scenes. The design follows a similar art style of past Avokiddo games, which is a paper cutout aesthetic. There are 8 scenes on the map that you need to follow and discover all the secrets and treasures, gems, buried chests, and mysteries.

Beck and Bo is a fun educational game for toddlers and preschoolers. Kids are invited to build beautiful, animated scenes by identifying characters, objects, and animals and placing them in the environment; and while they do that, they listen to their names and sounds! Piece by piece they bring to life colorful, fascinating scenes, full of sounds, animations, and fun interactive activities.

Kids will love building a snowman, getting fruits from the grocery store, putting the dog on the trampoline, watering the flowers in the backyard, controlling the traffic in the city center and discovering all the interactive objects within a scene (12 different scenes included).

The game is a combination of free play and puzzle. Each scene is gradually built as kids use both their logic and imagination to place objects and animals in the environment while they listen to their names and sounds. After a scene is complete, kids are rewarded by gaining access to the scene’s unique interactive album, where they can browse through the scene’s objects, listen to their names and sounds and see how these words are spelled.

This fun educational app offers a whole host of scenarios for creative pretend play. Playhouse in the bedroom and the backyard, pick and match food at the grocery store, swing, and slide at the playground. Kids will love to swim and play ball at the beach, control the traffic in the city, pick apples from the apple tree, win prizes at the theme park and so much more!

A few words from the founders of Avokiddo:


“At Avokiddo we strive to create quality and original playful experiences. We believe children learn best when they don’t realize they are actually learning. Knowledge must come naturally through exploration and unlimited trial and error. All our apps are based on this notion. In Thinkrolls logic puzzles, for example, kids are encouraged to try as many different strategies as they like, with no penalties or time limits until they get it right. During this creative process, kids not only explore a wealth of physics concepts but also develop important life skills such as problem-solving, concentration, patience, persistence, strategizing and creative thinking.”Dionisis Voulgaris, Co-founder, Owner, Director


“At Avokiddo we like to push the edge of how kids think and learn. We believe that it is never too early for kids to start exploring science concepts. An article on The Sunday Times sums up perfectly the idea behind our app DNA Play: ‘Sneak scientific knowledge under a child’s radar by turning it into a game’. In the guise of a hilarious monster creating a game, kids get their first glimpse of genetics, a scientific field that encloses the mysteries of life itself.” – Elpida Voulgari, Co-founder, Owner
