About
ATTENTION: THIS GAME REQUIRES HIGH-SPEED CONTROLLER TRACKING
Unfortunately, Steam removed some VR compatibility indicators, so we have to put it plainly here: Rainbow Reactor uses extremely accurate physics that only work with high-speed controller tracking. This means that throwing accuracy can suffer greatly from using wireless solutions like Air Play, Virtual Desktop etc - depending on your setup. Also, the game does not support lower frequency positional tracking like what is used in WMR for example. In short, it is advised to play this game using external tracking like lighthouses. On a side note, this makes this game an ideal tool to find out how good the inside-out tracking of HMDs and also the speed and reliablity of your wireless transmission is.

Normal operations have collapsed when the loading crane malfunctioned. Now it's up to the player, controlling a clueless Cleaner Bot, to load the reactor manually. Not an easy task, as the chromium balls which are full of precious energy are very volatile. Any mishandling could end in disaster…

Bon jeu. 100% en Français Beaucoup de stress quand les balles commencent à arriver rapidement
This is my dad's favorite game.
Rainbow Reactor to dość prosta na pierwszy rzut oka gra w łączenie ze sobą kolorowych kulek w trzy lub większoilościowe zestawy w której towarzyszy nam GlaDOSpodobna robotyczna postać chwaląca nas za udane łączenie lub przypominająca o tym ile razy łączeń musimy jeszcze wykonać albo ile szans nam zostało. Ogólnie dość męcząca postać swoim tonem mówienia bardzo przypominająca maskotkę Valve, ale wśród jej tekstów da się wyszukać easter egg z drugiej części filmu Obcy, co jest miłą niespodzianką, chociaż mimo wszystko wolałby by ta milczała. Gra oprócz tego, że jest logiczna, zmusza też do szybkiego podejmowania decyzji. Na rzut mamy raptem kilka sekund, bo jeśli będziemy zwlekać zbyt długo, to nie zdążymy złapać nadlatującej następnej piłki. Wymagane jest też od nas łączenia za sobą dwóch kolorów by uzyskać trzeci, który znajduje się na planszy, lecz gra nam go nie dostarcza. Trzeba jednak uważać co z czym łączymy. Niektóre kolory nie mieszają się ze sobą co oznacza kolejną karę. Do rzucania trzeba się przyzwyczaić. Kulki mają swoją wagę, więc należy poświęcić chwilę na umiejętne szacowanie siły zamachu, ale po dłuższej chwili faktycznie ma się wrażenie kontroli nad rzutem. Kontroli nie mamy niestety nad losowo pojawiającymi się innymi piłkami. Te spadają najczęściej w tylnej części planszy i jeśli ta jest zbyt zagracona kulka może nie znaleźć dla siebie miejsca i spaść poza obszar gry za co również jesteśmy karani. Raz zdarzyło mi się, że na początku gry losowo dorzucona piłka spadła z planszy. Nie jest to przyjemne dostawać po tyłku za błąd gry, zwłaszcza, że gdy od przejścia poziomu dzieli nas jeden rzut, to gra uzna, że losowa przeszkadzaja poturla się na zbocze stołu przez co musimy zaczynać od nowa. Podsumowując jest to przyjemna gra, ale im dalej będziemy grać, tym staje się coraz mniej rekreacyjna. Dobrze jest w to zagrać przez kilka minut, a później odłożyć i zająć się czymś innym.
Fun but needs more content/levels. Can be frustrating at times but that's more a product of being competitive.
Ein nettes Casual-Game für Zwischendurch ! In diesem Spiel muss man Bälle werfen und mit diesen in einer Matrix punktgenau treffen. Wie bei "Bejeweld" ergeben Reihen aus gleichfarbigen Bällen eine Kombi, die ab 3 gleichen Bällen vom Spielfeld gelöscht wird und damit Platz schafft. Kennt man von "Tetris". Je mehr Bälle durch eine Kombination gleichzeitig gelöscht werden, umso mehr Punkte erhält der Spieler. Es gibt ein paar verschiedene Spielmodi, die sich aber allesamt ähneln. Leider hab ich Pech mit dem Tracking meiner Controller. Die sind bei schnellen Bewegungen nicht mehr genau und überschwingen gern. Dadurch kann ich nicht die Kombinationen werfen, die ich brauche, sondern der Wurf geht oft ins Aus. Man hat 4 Fehlwürfe frei, beim 5ten Fehlwurf wird die Runde beendet und alle erspielten Punkte sind verloren. Das Spiel ist schön bunt, und der Soundtrack treibend. Mit den richtigen Controllern kann das Spiel eine zeitlang Spaß machen. Leider nutzt sich das Spielprinzip wegen zu geringer Abwechselung schnell ab.

So I fail if I throw a ball at the annoying robot? So much for fun. Dev edit: I just want to nail that robro with some paint balls my dude. Maybe add a gamemode next time where I can teach that smug bucket some manners.
Rainbow Reactor, developed by Tunermaxx Media GmbH in collaboration with Muikkumedia Oy and published by Tunermaxx Media GmbH, is a fast-paced virtual reality arcade experience built around precision, rhythm, and color coordination. Set inside a glowing futuristic reactor facility, the game places players in control of a compact robotic assistant tasked with stabilizing a volatile energy core. The concept is easy to grasp within seconds: grab incoming colored energy spheres and throw them into matching receptacles to keep the system running. Yet beneath that simplicity lies a surprisingly demanding test of reflexes, spatial awareness, and consistent hand-eye coordination. The entire experience revolves around motion-based interaction. Using VR controllers, players physically reach out, grab energy balls mid-air, and launch them toward the reactor’s intake points. The throwing mechanic is central to the game’s identity, and its success hinges on accurate motion tracking. Weight, angle, and velocity all matter, meaning that a casual flick of the wrist might send a sphere wide of its target. When the physics feel precise, landing a perfect throw delivers a deeply satisfying sense of control that few traditional arcade games can replicate. The tactile nature of VR amplifies engagement, transforming what could have been a simple color-matching exercise into an immersive physical performance. Visually, the game leans into a neon-infused sci-fi aesthetic reminiscent of retro arcade cabinets blended with modern synthwave design. The reactor chamber glows with vibrant hues, pulsing lights, and sleek metallic surfaces that reinforce the high-energy theme. This atmosphere is strengthened by an electronic soundtrack that syncs naturally with gameplay intensity. As levels escalate, music swells and tempo rises, creating a feedback loop between audiovisual presentation and mechanical challenge. Sound effects are crisp and responsive, making each successful throw, missed shot, and reactor surge feel impactful. Progression unfolds across multiple levels that gradually introduce new hazards and speed variations. Early stages ease players into the mechanics, but later sections demand quick decision-making and efficient movement. Energy spheres arrive faster, patterns become more complex, and mistakes carry greater consequences. The increasing tempo ensures that players must remain focused, especially when juggling multiple colors simultaneously. This rising difficulty curve gives the game a strong arcade identity, where mastery comes not from unlocking new abilities but from refining physical skill and reaction time. Replayability is a significant strength. Beyond the main progression, additional modes allow players to tailor difficulty settings, compete for high scores, and challenge friends in local multiplayer sessions. Party-oriented features make it particularly appealing in social VR environments, where alternating turns and leaderboard competition can spark friendly rivalry. Global score tracking further enhances longevity, encouraging repeat playthroughs in pursuit of tighter runs and optimized performance. Even a non-competitive exploration mode exists for those who simply want to appreciate the environment without the pressure of performance metrics. Despite its strengths, the experience is closely tied to hardware quality. Because precise tracking is crucial, lower-end or less stable VR setups can reduce accuracy and introduce frustration. Additionally, while the core mechanic is highly polished, it remains focused on a single central interaction. Players seeking deep narrative arcs or varied puzzle mechanics may find the gameplay loop repetitive over long sessions. The emphasis is firmly on arcade precision and skill refinement rather than expansive content variety. Ultimately, the game succeeds by embracing VR’s physical strengths rather than treating virtual reality as a novelty layer. It transforms a simple color-matching concept into a kinetic, rhythm-driven performance space where motion, timing, and sensory feedback converge. Its compact scope works in its favor, delivering an accessible yet challenging experience that rewards dedication and practice. For VR enthusiasts who appreciate physics-based interaction, competitive score chasing, and neon-drenched presentation, it stands as a focused and memorable arcade showcase that highlights how effective simplicity can be when executed with precision. Rating: 8/10
Whoops, I got this game for way too cheap! The key cost almost nothing so I wasn't expecting much ,but this game is exceptionally well made. Especially the graphics are fantastic, even though the game is apparently from 2019. The 80s synthie music is also banging. The match3 gameplay seems simple at first, but having to throw the colored balls in VR literally adds a whole new dimension to the genre. Also, things heat up pretty quickly and new features are introduced to make the gameplay more strategic. When I look at the scores people posted on the leaderboards, I'm getting the feeling the scoring system is also way more complex than I anticipated. As I said, my only gripe is that I feel I underpaid the devs, so I'm at least writing this review. And I'll probably buy their other game too!
It's alright..
