CryptoClub Daily Ciphers vs Tinrail

Have fun cracking secret codes! The messages here have been encrypted with mathematical ciphers. Find the patterns and use them to help crack the codes. Each day a new encrypted message is released. Messages include anecdotes about the history of cryptography, fun facts about science, and inspirational quotes. See how many days in a row you can successfully crack a message! All released messages are available through the app’s calendar. Every day of the week except Sunday has its own cipher type: Caesar, Additive, Keyword, Multiplicative, Vigenère, or Affine. The ciphers generally get more complicated as the week goes on. Sunday’s message is a wildcard that could use any of those cipher types. Don’t know what these ciphers are? No problem! The app has descriptions and examples of the patterns involved. It also has tools such as frequency tables that can help you guess letters, along with cipher tables to help you keep track of your guesses and look for patterns. CryptoClub Daily Ciphers is a companion app to the Daily Messages portion of the cryptoclub.org website. Check out the website for games, badges, and other activities that involve secret codes. An Internet connection is required to use this app. Data rates may apply. Consult your carrier for information about data rates.

Draw a railway with one finger and watch tiny trains bring a miniature countryside to life. Tinrail is a calm transit puzzle. Villages sprout across a small landscape, and each one fills up with parcels and passengers bound for somewhere else. Drag from a village to lay rail, tap to send out a locomotive, and the trains do the rest: they pick up, deliver and find their own way around your network. THE PUZZLE IS THE NETWORK Each stretch of track holds one train at a time, so a line that works with one engine can jam with three. Add junctions to give trains another way round, loops to keep traffic flowing, bridges to cross the river and tunnels to cut through the hills. Demolishing track gives most of it back, so redesigning is always an option. The countryside keeps growing. New land opens up, new villages appear, and yesterday's tidy line becomes today's bottleneck. Keep every village from overcrowding for as long as you can. FOUR WAYS TO PLAY - Levels: 1,000 boards, each with a delivery target. Pass it, then keep going to set your best. - Weekly Run: one countryside per week, the same for every player. - Daily: a fresh board every day. - Zen Garden: no fail state. Villages wait patiently while you build for the fun of it. SMALL TOUCHES - Follow a train from above, or ride along behind the engine at track level. - Pick your train colors. - Sound, music and haptics each have their own setting. - No account and no sign-in. ADS AND PURCHASES, PLAINLY Tinrail is free and supported by ads: a banner at the bottom of the screen and an occasional full-screen ad between runs. A short optional ad can also top up your rails, bridges, junctions or tunnels when you run low. One purchase, Remove Ads, removes the banner and the between-run ads for good. Other optional purchases: Speed Control (2x and 3x game speed), a Golden Locomotive color, and a tip jar for the studio. Made by Rusty Latch Games, a tiny independent studio.
