Arcade river tubing races
Grab a tube, hit the water, and float your way to the River Party. Steer through rapids, thread gates to build a multiplier up to 5X, bonk riverbank troublemakers with soda cans, and paddle hard when the Big Gator starts thumping behind you. Race CPU rivals, chase the Endless River leaderboards, and build your own rivers in the editor. Version 1.2 puts up to four tubers on the same river: race friends nearby or online with a room code, or tap Quick Race to take on anyone online with no code needed. Built with SwiftUI and SpriteKit, out now for iPhone, iPad, and iPhone Duo, with an Android version on the way.
Pirate fleet battles across nine wild realms
Hide your fleet, fire your volleys, and sink or plunder your way across the Nine Realms to win back the shattered Celestial Compass. Classic hidden-fleet battles get weird fast: icebergs, volcanoes, kraken attacks, flying ships, and meteor showers all change how each fight plays. Build your own captain, paint and fit your flagship, unlock 32 special items, and challenge a friend nearby, on one device, or online. Built in SwiftUI and SpriteKit, it's waiting on Apple's review now and coming soon to iPhone and iPad, with an Android version on the way.
A coloring book for kids and grown-ups
Color along with Miya, a cheerful miniature schnauzer who's always happy to help. Tap any shape to fill it with no spills, or draw freely with pencils, crayons, markers, watercolors, and glitter. Pick from twelve palettes or make your own, decorate with stickers, and earn badges as you go. Over 400 pages across 32 books, from big simple shapes for little hands to detailed mandalas for grown-ups. No ads, no accounts, and no data collected. Waiting on Apple's review now and coming soon to iPhone and iPad, with Apple Pencil support.
Golf's most fun scorecard
Track every round, run the game, and settle the bet before you're off the 18th green. Tap through every hole for the whole group at once, set up Nassau, skins, or best ball before you tee off and let Tap Bogey work out who owes who, and see exactly where your strokes go. Search thousands of courses with real tee and yardage data, and keep your clubs and bags in one place. The next generation of iGolfScorecard, rebuilt in SwiftUI and coming to iPhone and iPad in November, with an Android version on the way.
A growing arcade of themed slot-style games
Seven colorful, uniquely themed machines in one app: Panda King, BuffaYooooo, Miya & Friends, Alien Splat, Mini Trucks, Lucky 7, and Beers & Cheers. Pick a game, hit SPIN, chase Wilds, Bonuses, and multipliers, and unlock new games as you play. Built in SwiftUI on a shared Kotlin Multiplatform engine, with every spin verified by the server. Coins are play money only. Coming to iPhone and iPad in early 2027, with an Android release following soon after.
A cult 2007 arcade classic, reborn
AlienSplat is back. The tap-fest that launched alongside the very first iPhone returns, rebuilt from scratch in SwiftUI with sharper graphics, refined physics, faster action, and 250 handcrafted levels of escalating chaos across 15 arcs, all the way to a devastating nine-boss finale. Version 2.5 is ready for iPhone Duo, so you can splat aliens on the cover screen or unfold for the full-size battlefield.
