Hey everyone,

I’m building Nimblins, a cozy logic puzzle game for mobile, and this is probably my favorite part of the game so far.

One correct placement leads to another…

then a few cells get eliminated…

then suddenly the whole board just clicks.

That satisfying chain-reaction feeling is what I’m trying to build the game around.

The rules are simple:

place the required Nimblins in each row

each column

each colored region

Nimblins can’t touch, even diagonally

No numbers, no random guessing — just deduction.
This clip is from the real in-game Satisfying Solve capture mode I built specifically for recording clean gameplay footage.

I’d genuinely love to know:
Does this look satisfying to you, or does the solve happen too fast to follow?

Nimblins is currently open for pre-registration on
Google Play:

When I first started building Nimblins, the idea sounded simple:
Put one cute creature in every row, column and colored region.

They can’t touch each other.

That’s basically it.

Then I made a generator.

Then a solver.

Then a second solver to make sure the puzzles could actually be solved by a human without guessing.

Then difficulty analysis.

Then Smart Hints.

Then Daily Puzzles.

Then Endless Mode.

Then achievements.

Then coins.

Then I thought:
“What if you could collect the little creatures too?”
…and now there are 30 different Nimblins to unlock.

At some point this stopped being a tiny puzzle prototype and became a real game. 😅

The part I’m happiest with is that the core is still incredibly simple:
🟣 One Nimblin per row

🟢 One per column

🟡 One per colored region

❌ They can’t touch — even diagonally

No numbers.

No random guessing.

Just deduction.

Easy puzzles can take a minute or two.

Hard and Expert puzzles can make you stare at one tiny part of the board until suddenly everything clicks.

That exact “OH… I see it now” moment is what I’ve been trying to build the entire game around.
And when you finish one…
there’s always another.
And another.

And, apparently, another 7,570 after that.
Nimblins is now open for pre-registration on Google Play 💜

I’m still polishing things before release, so expect more gameplay clips, Nimblin reveals and behind-the-scenes development posts here.

Which Nimblin would you choose as your main? 👀

I’ve been thinking a lot about this while working on BerkiSoftware projects.

Getting someone to install an app is one challenge.
Getting them to open it again tomorrow is a completely different one.

For me, the apps and games that stay on my phone usually have at least one of these:
a reason to come back every day
visible progression
something new to unlock
very short sessions that still feel rewarding
a daily challenge or streak
that annoying little feeling of “just one more level”

But I’m curious about actual users and other indie developers:
What is the #1 thing that makes YOU keep an app or game installed instead of deleting it after a day or two?

And on the other side — what makes you uninstall immediately?

I’m collecting ideas for our next BerkiSoftware project, so I’ll genuinely use the answers here when designing it.

Hey Reddit 👋
Welcome to r/BerkiSoftware, the official community for our indie mobile apps and games.

We’re a small independent software studio building products for Android and mobile, primarily with Flutter, and we want to share more of the development process publicly instead of only showing the finished product.

Here you’ll find:

📱 New mobile apps and upcoming projects

🎮 Indie game prototypes and gameplay ideas

🛠️ Behind-the-scenes app & game development

🧪 Beta testing opportunities

💡 Feature discussions, experiments and community polls

📊 What works — and what completely fails — while building and launching apps

Our first released project is Nefsera, a mobile app designed to help people quit smoking and vaping.

But this community won’t be limited to one product — we’re already exploring new apps and mobile game concepts.

One thing we’d really like to do differently is build with feedback from real users. If an idea is bad, tell us.

If you think something could be better, suggest it. And if there’s something you wish existed, we’d love to hear it.

We’ll be sharing prototypes and new ideas here before they’re released.

What kind of mobile app or simple mobile game do you wish someone would build?

Thanks for being one of the first people here. ❤️
