One universe, many games: R-K8 Classic, SynthRacing-Club, RythmTape, SynthCity and local SynthTennis. Neon synthwave action – offline, no forced login.
Welcome to the R-K8 arcade universe – your offline hub of neon, synthwave and retro action on iPhone.
R-K8 is more than one game: It brings several modes together under one roof. Start with R-K8 Classic, jump into RythmTape, build your hall in SynthCity, and challenge friends in local VS SynthTennis. One download, many experiences – retro action, rhythm game, arcade management and local multiplayer.
◆ R-K8 CLASSIC
Play R-K8 Classic in retro neon style: charge batteries with cassettes, raise your Score, dodge waves, collect coins and power-ups, defeat bosses and chase high scores. Pick a difficulty, unlock skins, upgrade your fleet and clear Daily Challenges. Classic arcade gameplay with modern combos, style ranks and smooth flow – perfect for short sessions and long score runs.
◆ SYNTHRACING-CLUB
Hit the neon strip: wait for green, nail the launch, and swipe up to shift — race for respect. In the middle of the heat, dodge cops and roadblocks, unlock cars, and spend respect at Skill Events.
◆ SYNTHCITY – ARCADE STUDIO
Build your neon arcade, place cabinets, attract visitors, earn credits and grow your city’s influence. SynthCity blends idle tycoon and arcade management: prestige, events, VIP guests, marketing and the Neon Wave – claim districts and rule the neon city. Ideal when you want to switch between action and building.
◆ RYTHMTAPE – RHYTHM GAME
A music-driven rhythm/puzzle game: tap columns on the beat, move cassettes (matching top pairs travel together), clear lanes and keep the groove. RythmTape brings rhythm, timing and flow into your universe – short, addictive, soundtrack-heavy.
◆ SYNTHTENNIS – LOCAL MULTIPLAYER
Challenge friends in local VS (nearby P2P) or practice against the AI. SynthTennis offers duel fun with no account and no online matchmaking – fast party multiplayer for two devices.
