Seven puzzles people have been solving for decades, each with a clean modern board — and one shared progression that ties them together. Play a few sharp rounds, finish the day's tasks, open a chest, and see where you land on the board. SEVEN GAMES, THREE DIFFICULTIES EACH • Memory Match — flip two cards at a time and match every pair of gems. Six pairs on Easy, fifteen on Hard. • Sudoku — a 6x6 grid where every row, column and 2x3 box holds 1 to 6 exactly once. Harder means fewer clues. • Lights Out — tap a tile and its four neighbours flip with it. Turn every light off, from a 4x4 grid up to 6x6. • Mastermind — crack a secret code of coloured pegs from feedback alone. Up to eight colours across five slots. • Tower of Hanoi — move the stack one disk at a time, never a larger disk onto a smaller one. Six disks take 63 moves. • Simon — watch the pattern, repeat it, watch it grow. Reach round 16 on Hard, where it also flashes faster. • Sliding Puzzle — slide the tiles back into order around the one empty square. Every game records your moves, your mistakes and your time. Fewer moves and less time make for a better record, and the difficulty is recorded with it, so boards only ever compare like with like. Hard unlocks at level 5. ENERGY, TASKS AND LEVELS A round costs one energy out of a bar of fifteen, and the bar refills on its own — so a session has a natural end instead of running until you finally put the phone down. Daily tasks ask for something specific: win Lights Out ten times, finish a game under a time, play the one you keep avoiding. Finishing a task pays fires, coins and XP. Every completed game feeds the XP bar too, and levels release milestone rewards along the way. FIRES AND LEADERBOARDS Wins earn fires, and fires are what rank you. There are four boards — Week, Month, Season and All time — and your own row is lit so you can find yourself without scrolling. The week's top three take chests, coins and XP home when it settles. CHESTS, GEMS AND SKINS Chests come in five tiers: Wooden, Iron, Silver, Golden and Platinum. Earn them from tasks and milestones, or buy them in the shop with the coins you have collected. Each one opens into items of a rarity, and the rare drops get the loud treatment. Keep the gems to complete a collection, wear the skins, frames and banners on your profile, or sell the spares back for coins. YOUR ACCOUNT Sign in with an email address and a password, or with Google or Apple if you would rather skip the form. Your progress, your loot and your place on the boards live on our server, so they follow you from one phone to the next. You can delete your account from inside the app at any time — Profile, then Settings, then Delete account. You get a 15-day grace period to change your mind, and after that the account and its data are erased. COMING SOON Multiplayer is on the way.
