SPARKMIND is a free idle game where you grow a living network of light. Every neuron fires pulses that travel along the branches to the core, so you can literally watch your production flow. Evolve from a worm brain to a human mind, upload yourself into an AI and finally spread across the cosmos.
Research
How to Play SPARKMIND
- Tap the core to make sparks, then press Grow Neuron. Every neuron sends pulses of light to the core by itself.
- Evolve: every few neurons your brain reaches a new level that unlocks new features and multiplies your sparks.
- Buy upgrades: 130 one-time upgrades unlock as you grow, from Dopamine and Serotonin to Tensor Cores, Chain of Thought and Dark Matter.
- Place special neurons: tap a neuron to convert it. Specials boost every pulse that passes through them, so place them where many branches meet.
- Complete missions and catch the golden Epiphanies for big rewards.
- Dream once you reach the Primate level to earn Insight and become permanently smarter.
The 3 Eras
| Era | Levels | What changes |
|---|---|---|
| 🧠 Biological | Spark, Worm, Insect, Fish, Crow, Primate, Human | Organic glowing neurons |
| 💾 Silicon | Transistor, Microchip, Perceptron, Deep Network, GPU Farm, Transformer, LLM, Multimodal AI, AGI | Your brain becomes a circuit board with chips and data packets |
| 🌌 Cosmic | Superintelligence, Quantum Mind, Dyson Brain, Matrioshka Brain, Galaxy Mind, Universe Mind, Omega Point | Neurons become stars around a black hole |
Special Neurons
| Neuron | What it does |
|---|---|
| 🔆 Amplifier | Multiplies every pulse that passes through it |
| 💎 Crystal | Pulses can turn critical and become worth much more |
| 💓 Pacemaker | Its whole branch fires faster |
| 🔋 Capacitor | Stores 10 pulses and releases one huge pulse |
| 🌱 Sprout | Grows free neurons over time |
| 📡 Antenna | Attracts and catches Epiphanies |
| 🖥️ GPU | Doubles every pulse that passes through it |
| 🧿 Attention Head | The bigger its branch, the stronger the boost |
| ⚛️ Quantum Core | Teleports pulses straight to the core |
| 🕳️ Black Hole | Swallows 25 pulses and releases a monster pulse |
| 🌟 Star | Goes supernova every minute |
Tips
- Put Amplifiers and GPUs close to the core. Every pulse from the branches behind them gets boosted.
- Pin a special neuron so new neurons grow behind it and multiply its effect.
- Buy cheap upgrades first. The Buy all button picks them in order of price.
- Do not rush your first Dream. Waiting until you earn 3 or more Insight makes the next run much faster.
- Come back every day for the daily reward streak. Day 7 gives a Frenzy.
Frequently Asked Questions
What is SPARKMIND?
SPARKMIND is a free idle (incremental) game in your browser. You grow a glowing network of neurons that sends pulses of light to a core. That light is your currency, and you use it to grow your brain, buy upgrades and evolve.
How do I play SPARKMIND?
Tap the core to make sparks and press Grow Neuron to add neurons. Each neuron fires pulses to the core on its own. Tap a neuron to turn it into a special neuron, such as an Amplifier or a Crystal, or pin it so new branches grow there.
What are the eras in SPARKMIND?
There are 3 eras and 23 levels. In the Biological Era you evolve from a worm brain to a human brain. Then you upload your mind to silicon and become an AI (Transformer, Large Language Model, AGI). Finally, in the Cosmic Era, you grow into a Dyson Brain, a Galaxy Mind and the Omega Point.
What does Dream do?
Dream is the prestige system. It resets your neurons, sparks and upgrades, but gives you Insight. Each Insight permanently boosts your sparks, and you can spend it on a constellation of 28 perks such as Auto-Grow or Twin Sparks.
Does SPARKMIND keep playing when I close it?
Yes. Your brain keeps earning sparks while you are away, at a reduced speed that you can improve with upgrades. Your progress is saved in your browser.
Is SPARKMIND free?
Yes. It is free, works on desktop and mobile, and needs no download or account.
