This is an educational game that allows you to learn the UK map as if you play a jigsaw puzzle produced by Digital Gene. This game is designed to be simple yet fun to play. Not only people who like the map, but also who are not good at geography can enjoy playing it. The app is best suited for people who want to learn the UK map or students who want to get ready for the exams. Or why don't you try this game to stay sharp during your spare time? You can improve your knowledge as you play the game aiming for the best time or compete against players from all over the world. You can also collect picture panels when you satisfy certain conditions. So do your best to get all of them. There are various modes available, including a [Beginner] mode with the region names and boundaries, a [Expert] mode testing only region names, and an [Master] mode without hints. Area is divided "England", "Scotland", "Wales" and "Northern Ireland". When you're stuck on finding the location of a state, use the [Assist] function. It will help you to navigate the correct location without hassling yourself. However you will be added a 30 seconds penalty when you use the [Assist] function. If you want to achieve a higher ranking, it'd better not to use this function. (*) City of London is omitted from the game for the sake of expediency.

A puzzle game where you UNDERSTAND ciphers by solving them - not by reading about them. From the Caesar cipher to RSA and hashing, crack classic and modern ciphers one stage at a time, and the way each cipher works clicks into place. Work out the key from a clue and enter it, spot letters with frequency analysis, reverse-look up a grid - relive that "aha" moment of decryption again and again. [ 9 ciphers, 57 puzzles ] Classic ciphers - free, 40 puzzles - Caesar (10) - Shift letters; work out the shift from the crib and enter it - Vigenere (10) - Polyalphabetic with a keyword; guess the key - Substitution (8) - One-to-one swap; crack it with frequency analysis - Transposition (6) - See through the reordering - Polybius Square (6) - Letters to numbers via a 5x5 grid; reverse-look up Modern ciphers - 17 puzzles - XOR (6, free) - Exclusive OR; XOR with the key to recover the text - Public-Key, simplified RSA (4, Modern Cipher Pack) - Work out the number locked with the public key - Hash Function (4, Modern Cipher Pack) - Feel one-wayness; find an input that collides to the same output - Block Cipher, AES-style (3, Modern Cipher Pack) - Step through add-key, substitute, and permute, one move at a time [ Features ] - Explanation right after you solve - history, real-world usage, weaknesses, and the bridge to modern tech - Staged hints - the first level is free; reveal more step by step when stuck (keeps the "I solved it" feeling) - No ads at all while you are solving a puzzle - designed to preserve focus - Achievement badges and stats (including your daily solving streak) - iPhone and iPad - Japanese and English (UI, puzzle text, and hints; follows the device language) - Ciphertext shown in an easy-to-read monospaced font [ Who is this for ] - Anyone who loves puzzles and riddles - Students and engineers curious about cryptography and security - People who want quick brain-training in spare moments [ Part of the Raku Series ] The third information-systems title of the Raku Series. Knowledge from ARURAKU (algorithms) and DATARAKU (data structures) pays off in NazoRaku's decryption - hashing and modular exponentiation tie ciphers back to the fundamentals.
