# Sliding Puzzle

This is my version of a sliding puzzle.
A sliding puzzle is based on a number of tiles (15 in this case) which are scrambled.
The objective of the game then is to slide the tiles around and get back to the original image.
As an image I took a photo of an apple in front of a black background.For more information on sliding puzzles, check this Wikipedia entry.

## Controls

• ‘F1’ takes a screenshot,
• ‘F2’ starts and stops scrambling the image,
• ‘F3’ solves the puzzle,
• Mouse clicks slide tiles.

# Factorization

Playing around with prime numbers, I created this simple factorization program.
The interesting thing about prime factors is that they are unique. There can only be one way to multiply prime numbers to get 𝑛 where $n\in\mathbb{N}$ and $n\geq 2$ (excluding the commutative property).For example, $2\cdot 3\cdot 7=42$ and that is the only way to multiply prime numbers to get to 𝟦𝟤.

This game is a clone of the famous international hit Flappy Bird.
You control the little pixel-bird, while it flaps through three different scenes and tries to avoid deadly pipes. Your score is measured by how many pipes you can pass.

## Controls

• ‘Escape’ pauses and resumes the game,
• ‘F1’ takes a screenshot,
• Up arrow key makes the bird flap.

# Prime-Generating Formula

(April Fools’!) I came up with this interesting prime-generating formula. It uses the constant 𝜉 and generates the primes in order!

The constant’s approximation.

The formula $p_n$ calculates the 𝑛-th prime.

The first few values for $p_n$ when starting with 𝑛 = 𝟢 are as follows.
