Pascal Numbers Triangle

Pascal Numbers Triangle is simple numbers puzzle involves with arranging numbers in a triangle. Full version has more difficult levels. Move the letters by tapping/touching them (not drag). When you tap/touch two numbers they will get swapped. Use size option to resize the letters so that if device screen is not enough to include bigger size numbers (more than 5 rows). There are three puzzles in this app.

1) Pascal Triangle (relatively easy)

Each number is sum of the two numbers above it.(Since triangle is symmetric triangle there are two solutions for each game)

2) Pascal Subtraction Triangle (similar to pascal triangle with minor difference)
(relatively difficult with more rows)

Each number is absolute differnce of the two numbers below it. (If traingle is symmetric triangle then there are two solutions for each game)

3) Pascal Addition Triangle (similar to pascal triangle with minor difference)
(relatively easy)

Each number is sum of the two numbers below it. (If triangle is symmetric triangle then there are two solutions for each game)

Numbers can be moved by tapping them. Numbers are swapped when you touch/tap two numbers. Size and number of rows can be increased/decreased by selecting size/rows options respectively.
