DOP 2: Delete One Part

Review by eFreeware

If you like the idea of a puzzle you can pick up for a few minutes and put down without penalty, DOP 2: Delete One Part is built around exactly that. You drag a finger across the screen to rub out part of a cartoon drawing, and whatever was hidden behind that patch becomes visible. The developer, SayGames Ltd, has pitched this at a broad audience, from teenagers to older players who want something to keep their mind ticking over.

What you get is a free download with hundreds of levels promised, a cartoon look, and a simple eraser mechanic that carries the whole thing. It is rated Teen and has been downloaded more than 100 million times, with a 4.5 average across 763,076 ratings. That is a lot of people who have found something here worth their time.

I would point this at readers who enjoy visual riddles more than word or number puzzles, and who do not want a game that punishes mistakes. The appeal is the small moment of surprise when the eraser uncovers something you did not expect, and the developer has built the entire experience around repeating that moment.

How the swipe-and-reveal puzzles work

The interaction is about as stripped back as a puzzle game gets. You touch the screen and drag to erase a section of the drawing, and the image underneath is revealed. The game is built around a single simple interaction. The developer describes the eraser as the tool that unlocks each scene, and the challenge comes from working out where to swipe and what the new information tells you.

That simplicity is the point. Because you can only remove things, the puzzle is really about deduction: you look at the whole picture, guess which part is hiding the answer, and erase it. The developer says the game can look easy at first and then turn out to be trickier than it appears, and that matches the kind of misdirection these puzzles tend to rely on.

The safety net is worth noting. If you erase the wrong area, the picture simply resets, so there is no way to fail a level. The developer frames this as a game meant to make you think rather than make you frustrated, and that reset behavior is what keeps the tone light. It also means the difficulty curve is about how long you stare at a scene, not about whether you can recover from a mistake.

Hundreds of scenes and the twists inside them

The game promises hundreds of levels, each one a self-contained cartoon scene with something concealed in it. No two puzzles are alike, and each level asks you to approach the problem in a fresh way. From the examples given, that variety comes from the situations rather than the controls: a bank robbery, a wife hiding something from her husband, a genie trapped in a lamp, pottery being shaped, a murderer to be caught.

The first thirty levels are said to include the genie, the pottery and the murderer, which suggests the game front-loads its more memorable setups. Beyond that, each swipe uncovers a deeper layer of the story in the drawing, so the reward for solving a level is often narrative rather than mechanical. You are not just finding an object; you are finding out what is going on.

The presentation supports that. The scenes are drawn in a cartoon style with cute animations, and the whole thing is designed to feel relaxing rather than tense. There are also optional settings for music, sound effects and vibration, which lets you decide how much feedback you want while you play. None of that changes the puzzle, but it does let you tune the experience to your surroundings.

Ads, purchases and what the download includes

DOP 2 is free to download and contains advertising. It also offers in-app purchases.

I would not treat the ads as a reason to avoid it, but they are a reason to set expectations. If you find interruptions grating in a game you play in short bursts, that is the main thing to consider.

What you are getting for the download is the full swipe-and-erase loop, the cartoon scenes and the sound and vibration toggles. The most recent update lists only bug fixes and performance improvements.

Who will get the most out of it

This is a game for people who enjoy the moment of realization more than the challenge of execution. If you like spot-the-difference pictures, escape-room style deduction or lateral-thinking riddles, the swipe mechanic will feel natural. The developer explicitly mentions teens and seniors, and the absence of failure states means it works for players who do not want to be beaten by a level.

It also suits short sessions. Because levels are self-contained and there is no progress to lose, you can work through a few scenes while waiting for something else to happen, or play for longer stretches when you want to. The optional sound and vibration settings mean you can keep it quiet in public or turn it up at home.

The flip side is that the game is narrow by design. It does one thing: erase, reveal, deduce. If you want a puzzle game with layered systems, story choices or competitive scoring, this is not built for that. The appeal is repetition of a single satisfying trick, and how long that holds your attention depends on how much you enjoy the trick itself.

The Teen rating and the cartoon style suggest the content stays within broad bounds, though the developer's own examples include a robbery and a murderer, so the themes are not entirely gentle. That is worth knowing if you are considering it for a younger player.

What holds up and what does not

The strongest part of the design is the reset-on-mistake rule. It removes the anxiety that comes with mistakes and keeps the focus on observation. The developer's claim that there is no way to fail is accurate to how the game is described, and it is a smart choice for a game aimed at such a wide age range. The cartoon art and animations also give the scenes enough personality to make the reveals land.

The weak spot is variety of interaction. Every level uses the same eraser, and the only thing that changes is the picture and what is hidden in it. That is fine for a while, but the developer's promise of hundreds of levels means the game has to keep finding new ways to surprise you with the same tool. Whether it manages that over the long run is the main question.

The ads and in-app purchases are the other consideration. They are part of the free model. If you are sensitive to interruptions, that will shape how you feel about the game more than any puzzle will.

A calm pick for casual puzzle fans

DOP 2: Delete One Part is a well-pitched casual puzzle game. It takes one idea, the swipe-to-erase reveal, and builds hundreds of scenes around it. The lack of failure states, the cartoon presentation and the optional sound settings all point to a game designed to be relaxing rather than demanding. The 4.5 average from over 763,000 ratings suggests a lot of players agree.

I would recommend it to anyone who wants a low-pressure puzzle to dip into, especially if you enjoy visual deduction and do not mind ads in a free game. It is less suited to players who want mechanical depth or a game that changes as they progress. For what it sets out to do, it does it cleanly, and the recent update suggests it is still being looked after.
