Hole Stars: Puzzle Game

Review by eFreeware

There are evenings when a big strategy game or a story-heavy adventure is more than I want to deal with. What I want instead is something small and tidy, a game I can pick up for a few minutes, finish a level or two and put down without carrying anything around in my head afterward. That niche is crowded, and most of what fills it either asks for constant attention or nudges you toward spending.

Hole Stars comes from Moon Active. It is a free puzzle game in which you steer a black hole around a level and swallow whatever fits inside it. The premise is simple enough to explain in one sentence, which is usually a good sign for this sort of game.

It has more than 5 million installs and a 4.7 average from over 68,000 ratings, which suggests the formula has landed with a lot of people. It arrived in December 2025 and the developer describes it as a relaxing, satisfying break-time game rather than anything demanding. That is the pitch, and it is a familiar one.

A black hole that grows as it eats

The central idea is that your black hole is not a fixed tool. It starts small and grows as it collects things, and the size of the hole decides what it can swallow. Early on you are picking up small objects; later, once the hole has expanded, larger items come within reach. That progression is the whole engine of the game, and it is the reason the levels are described as puzzles rather than simple collection.

Every level is full of things to gather, hazards to work around and puzzles to crack. The levels are spread across different worlds, which gives the game a visual reason to keep moving forward. The appeal is meant to come from the act of clearing a board.

What I like about this setup is that it gives every level a natural shape. You start constrained, you work outward, and the board opens up as you go. It is the sort of structure that can make a simple mechanic feel like it has momentum, and it is why the game is likely to appeal to people who enjoy sorting games and brain teasers.

How a level actually unfolds

You move the hole by swiping, and the hole follows your finger around the level. As it passes over objects they are swallowed, and the hole gets bigger. The larger it becomes, the more of the board it can clear in a single sweep, so the middle of a level tends to feel faster and more expansive than the opening moments.

The complication is the clock. A timer runs on every level, and you have to clear it before the clock stops. That turns a game that looks calm on the surface into something that asks you to think about route and order. Where you go first matters, because a poorly chosen path can leave you circling back for items you passed when the hole was too small to take them.

Blockers and tricky objects are there to disrupt that planning. The developer describes them as things to avoid and outsmart. Boosters exist for the moments when a level does not go your way, and they are presented as a way to handle tough spots rather than a core part of every run.

Working out the order and planning your route are part of the experience. That fits the genre: part of the satisfaction is in reading a board before you move, not just reacting to it. The result is a game that sits between action and light strategy.

The atmosphere the developer is going for

Moon Active leans hard on tone. Fluid movement, sharp artwork and soft ASMR-style audio are all part of the package, and the game is described as relaxing and satisfying. That combination is deliberate: the mechanic is about consumption and growth, but the presentation is meant to be soothing rather than aggressive.

That contrast is the most interesting thing about the design. A timed game is not inherently relaxing, and the developer seems aware of it, which is why the sound design and animation are given equal billing alongside the puzzles. It is pitched as suitable for short sessions as well as longer streaks, so the game is meant to work whether you have five minutes or an hour.

I would expect the ASMR framing to be the dividing line for a lot of players. Some people find that style of sound genuinely calming and will keep the volume up; others will find it distracting and turn it down. Either way, it is clearly a considered part of the experience rather than an afterthought.

Competition and the leaderboard

Beyond the level progression, the game includes a social and competitive layer. There is a leaderboard, so you can measure speed and puzzle skill against friends. This is an optional way to push yourself further, not the main event.

That is a sensible structure for this type of game. The levels give you something to work through at your own pace, and the leaderboard gives you a reason to replay and refine. Racing for a faster clear is a different kind of challenge from simply finishing a board, and it is the part most likely to keep a certain kind of player engaged after the novelty of the mechanic wears off.

The game is rated Everyone, so the competitive side is presented in a light, friendly way rather than as a hardcore ranking system. If you are the sort of person who enjoys shaving seconds off your own best time, this is likely to be where the long-term appeal sits.

Cost, ads and purchases

Hole Stars is free to download. It contains advertising and it offers in-app purchases. Those are the two things worth knowing before you install it, and they are the only monetization details given.

What matters is that you are not paying up front, and that the game is not presented as a one-time purchase.

Boosters are mentioned as a way to handle difficult levels. I would simply note that the game is free to try and that any money you spend beyond that is a choice you make in the moment.

Where the fun is likely to run out

The honest limitation here is the one built into the premise. A game about swallowing objects and clearing boards is only as varied as the levels and the objects within them. There are dozens of puzzles across different worlds, and the appeal will depend heavily on how inventive those levels remain once the core loop is familiar.

The timer is another thing to weigh. A countdown creates tension and gives each level a clear objective, but it also means the game is never truly passive.

The competitive layer is similarly a matter of taste. Leaderboards and friend comparisons add a reason to replay, but they also introduce a social dimension that not everyone wants in a wind-down game. None of this is a flaw exactly; it is a question of whether the mix matches what you are looking for.

A tidy fit for short, timed puzzle sessions

Hole Stars is a free, ad-supported puzzle game with in-app purchases, built around a single strong idea: a black hole that grows as it eats and has to clear a timed level. It is relaxing and satisfying, with smooth animation and ASMR-style sound, plus a leaderboard for players who want to compete with friends.

It suits people who want a lightweight game they can dip into for a few minutes, especially if they already enjoy sorting games and brain teasers and do not mind a countdown. The growing-hole mechanic gives each level a natural arc, and the level boosters provide an escape hatch when a board goes badly.

If you prefer your puzzles untimed and completely unhurried, the clock is the thing to think about before you install. For everyone else, it is a free download with a clear hook and a competitive layer waiting once the levels run out.
