Denis's Adventures - Animals Puzzles is an educational jigsaw mobile game developed for my son Denis. His first game played on a tablet was a puzzle game with animals, followed by a lot of other jigsaw puzzle games. Denis's Adventures - Animals Puzzle is designed for preschool children aged between 1 and 6 years old. The game was tested by Denis and other kids of different ages and they gave us feedback in every development step. They really enjoyed the puzzle game, so we trust your kids will love it, too. The game has four parts: Farm animals, Wild animals, Ocean animals and Birds. Every section has 8 puzzles with different animals from around the world. After each puzzle is finished, the kids receive some information about the animal like: its habitat, what it feeds on, etc. The game has 3 stages of difficulty: Easy - 4 pieces of puzzle, Medium - 8 pieces of puzzle and Hard - 16 pieces of puzzle.
