Slidethrum – Sliding Puzzle
Sliding puzzle, 26 pictures
Free · Designed for iPad. Not verified for macOS.
New: optimized for iPhone Duo – unfolded, the board fills the whole display; in landscape you see every solved puzzle on the left.
Slidethrum brings the sliding puzzles from schiebepuzzle.com by the EÖDL (First Austrian Umbrella Association for Dyslexia) to iPhone, iPad and Apple TV.
The pieces are mixed up and one square is empty. Slide a piece next to the gap into it – if it is further away in the same row or column, every piece in between slides too. The puzzle is solved when everything is back in order.
26 PUZZLES
• Classic numbers and gold numbers in red, blue and green
• Letters: capitals, lowercase and wooden letters from A to Z
• Animals such as a chihuahua, bear, fox and pony
• Easter and seasonal pictures
HOW TO PLAY

OPTIMIZED FOR IPHONE DUO
Closed, you play on the outer display. Open in portrait, the board fills the whole display. In landscape, info, controls and the "Solved" list sit on the left and the board is on the right for tapping. The app rotates in every direction.
WHAT SLIDETHRUM TRAINS
According to the experts of the EÖDL, number and letter puzzles train visual sequencing: numbers and letters have to be put into the right order. Picture puzzles train visual discrimination and visual sequencing. There are different levels and no real time pressure. The game does not replace individual dyslexia training.
