The same board for everyone, every day. One attempt. How far you push it is up to you. SAPPER is minesweeper with no edges. Each day the world gets one shared minefield, identical for every player. Start on safe ground and sweep outward. The farther you go, the denser the mines and the more every safe tile is worth. A Cash Out button sits on screen the whole time. Bank your score, or push one more row into the unknown. Hit a mine and the run ends with half of what you had not banked. Cash out and all of it is yours. That choice is the whole game. Then see how your run stacks up and share the shape of the territory you cleared. Miss a day and it is gone. Tomorrow there is a new board, the same for everyone, again. MORE WAYS TO PLAY Endless: a fresh board every run, whenever you want. Chase your personal best. Rush: two minutes on the clock. Clearing tiles buys time, mines cost it, and there is no Cash Out. How long you last is the score. The Daily is free for everyone, forever. One single purchase unlocks the full game, Endless and Rush included, for good. Your first day comes fully unlocked, so you know exactly what you are buying. No subscriptions. EVERY CASH-OUT LEAVES A MARK Cash out on purpose and the expedition is preserved in the Archive: the shape of the territory you cleared, the score, how far you pushed. Every banked point grows your lifetime Vault, and Vault milestones unlock app icons and board editions. Everything is earned by playing. Nothing is sold, and nothing changes the odds. iCloud keeps your Archive, Vault, and stats in sync across your devices. BUILT TO FEEL CALM No timers while you play. No explosions. No ads. Just a clean board, quiet haptics, and a real decision on every tile. FEATURES Daily seeded challenge, one board shared by the whole world Shareable result cards showing the territory you cleared Infinite drag-to-pan board Scoring that rewards going deeper Expedition Archive that preserves every cash-out Lifetime Vault with earned app icons and board editions Board editions found out on the board, not bought iCloud sync across your devices Game Center leaderboards Dark Mode and Dynamic Type support Plays fully offline Sweep.

Battlefleet Duo is a turn-based naval strategy game that brings the familiar board game of hidden fleets, careful deduction, and tactical choices to a living 3D ocean. MADE FOR IPHONE DUO • Tabletop mode: your fleet on the lower screen, the enemy’s waters standing up in front of you. • Full screen mode: takes advantage of the big screen with enhanced 3D graphics and effects. • Two players face to face: each with their own board, just like the classic game. • The game camera and layout adapt as you fold the device. • Bonus Classic mode: switch the ocean for the plastic board from the original box, pegs and all, for a hit of nostalgia. Battlefleet Duo also adapts to any iPhone and iPad. THE BATTLE Watch each shot fly from the ship that fires it. Hits bring fire and smoke, and defeated ships sink beneath the waves. Battle in daylight, at dusk or under moonlit skies, with storms, rain and lightning. Place five ships in secret on a 10×10 grid, then take turns firing into the enemy’s waters. Follow the clues from your hits and misses, uncover their ships, and sink their fleet before they sink yours. Choose Standard rules for the familiar game, or Enhanced rules where each ship brings its own weapon: an air strike hits three squares in a line, a torpedo travels down a column to the first hull, a star shell gathers intelligence, and a missile targets one square every turn. Keep each ship afloat to retain its weapon. PLAY YOUR WAY • Solo: challenge the computer on Easy, Medium, or Legend. • Face to face: on two devices over the local network. • Pass and play: one device between two players, with fleets hidden at every handover. • Online: invite a friend or find an opponent through Game Center. Continue unfinished battles later, whenever you’re ready for your next move. MAKE THE FLEET YOURS Visit the Shipyard for alternative ship designs, paint schemes, shot effects and custom markers on the opponent’s grid. Complete daily and weekly orders, earn sovereigns to spend in the Shipyard, and rise from Cadet to Admiral and beyond. Your progress syncs through iCloud across devices using the same Apple Account. PLAY FREE EVERY DAY Play two free battles each day. Unlock unlimited battles with a one-time in-app purchase. No subscription. Optional sovereign packs are available for customisation.
