No annoying ads, no data collection. Endoku is a single-player logic puzzle played on concentric rings, where you place numbers so each radial line adds up. Just two rules: • Each ring uses its set of numbers exactly once. • The cells along each radial line must add up to the same target. From these two simple rules, pure logic — never guessing — leads you to the one solution. Every puzzle is generated to be solvable by logic alone. Fresh for anyone who bounced off Sudoku, and meaty enough for anyone a little bored of it. Features: • Four board modes: Intro (2 rings) / Basic (3) / Advanced (4) / Expert (5) • Three difficulties (Easy / Medium / Hard) • Pencil marks (candidate notes) to work through the tougher boards • A fresh Daily puzzle with a calendar and streaks • A built-in strategy guide • Calm music and satisfying sound effects (each toggleable) • Gentle haptics • A calm, easy-on-the-eyes board • Japanese / English, portrait & landscape Intro and Basic (Easy/Medium) are free. A single one-time purchase unlocks all modes and difficulties, daily puzzles, the strategy guide, and music & sound.

PixelFlip is three retro arcade games stacked on top of each other, and the only way out of one is down into the next. You start on a pinball table. Drain the ball and the game doesn't end. You fall into Breakout. Lose the ball there and you drop again, all the way down to Hurdle, where you run, jump and try not to crash. Make it through and you can climb back up to where you started. A single game can take you through all three, more than once. It starts out friendly. It doesn't stay that way. The longer you survive, the faster and tougher everything gets, so every run is a race to bank as many points as you can before it all catches up with you. Only a crash in Hurdle costs you a life, and you get three. PLAYS GREAT ON iPHONE DUO PixelFlip supports both screens on iPhone Duo. Play folded on the outer screen, or open it up and use the big inner screen for a wider view of the table. The table, the bricks and the controls are sized to fit either one, and you can pause, fold or unfold, and pick up right where you left off. PINBALL Flippers, bumpers, targets and a launcher, the way you remember them. Light up all three wall targets if you can. Rack up enough points and one bumper starts pulsing. Hit it and your flippers swap sides until you sort yourself out. It isn't the only trap on the table, either. And if your last ball arrives with a big enough score, you'll be offered a choice. Choose carefully. BREAKOUT A board of bricks in the shape of a sun, a crescent moon or a star, with gates behind it. Every shape is worth the same, so the board changes but the stakes don't. Some gates help you. Some really don't. Catch falling power-ups for a longer paddle or extra balls, and try to dodge the one that shrinks your paddle. Breakout remembers which bricks you've already broken, so coming back is never quite a fresh start. A short 3-2-1 countdown before every serve gives you a second to get your paddle in place. HURDLE A run along the bottom of everything. Jump the hurdles, grab gold rings for bonus points, and hang on as the pace keeps climbing. KEEP SCORE • A top-10 high score table with three-letter initials, just like the arcade. • A Game Center leaderboard to see how you stack up against friends and everyone else. • 16 achievements. Some are obvious. A few only make sense once you've earned them, and one stays out of sight until you do. • Save & Quit in Pinball before any launch, with two save slots so two people can each keep a run going. Each save can be used once. THERE'S MORE IN HERE PixelFlip has hidden games tucked away in it. We won't tell you where. The Game Map in Settings shows what you've found and puts a question mark on everything you haven't. It won't tell you how to find the rest. Poking around is half the fun.
