TPPD
Creation of new logic puzzle types

Logic puzzle „Rooftops“ 9×9 ▲

Instructions: We are looking at a grid of 9×9 boxes. The boxes symbolize buildings with heights ranging from 1 to 9. The objective is to fill in the correct height of each building, considering that each height appears just once in each row and each column. The small digits in the upper left corners of the boxes reflect the amount of buildings the respective building can oversee in its row and column.

Try out here at Logic Masters Germany.

Logikrätsel „Low Sums“ 9×9 ▲

Instructions: We are looking at a grid of 9×9 boxes. The objective is to fill the grid with digits so that each column and each row contains all of the digits from 1 to 9. The preprinted number in each box reflects the sum of the orthogonally adjacent smaller digits. Casually speaking: the smaller digits feed the preprints of the neighbouring larger digits.

Project description



Logic-based puzzles like Sudoku are a strange yet fascinating invention: While the grids appear strict and unemotional, each newly fund number triggers our brains reward system and makes solving the puzzles a must.

Apart from Sudoku, there is a huge number of other great logic puzzles. New types get invented all over the world – with „Rooftops“, „Low Sums“ and „High Sums“, TPPD finally joins in the scene. „Low Sums“ was developed in cooperation with Christian Halberstadt, chairman of Logic Masters Germany and co-organizer of the German Sudoku Championships.

All three puzzle types can be test-played in the puzzle portal of Logic Masters Germany.
