Mind Stack
Stack good habits. Dodge bad ones. Build your day before it all collapses.
How to Play
Items fall toward your tower. Tap to drop the good ones onto the stack. Let the bad ones pass — don't tap.
Every drop needs to land clean, too: miss the tower's centre and the block width narrows. Too narrow, and the tower topples even if your stability is fine.
Two ways to lose: a bad habit you dropped by mistake, or a good one you missed the timing on. Precision matters as much as restraint.
The Science Behind Mind Stack
Every falling item asks the same question in half a second: act, or don't? Mind Stack is a physical version of the Go/No-Go paradigm, a foundational test of response inhibition — the ability to stop yourself before you act, not talk yourself out of it afterward.
It's a genuinely different skill from what Stroop-style games test. Colour Liar and Word Lock put two competing answers in your head and ask which one wins. Go/No-Go doesn't offer two answers — it asks whether you should be answering at all. That distinction, act versus don't-act, is closer to resisting a notification than resolving a conflict.
The stacking layer adds something most lab versions of Go/No-Go skip: execution quality. A correct decision to tap still has to land centred, or the tower narrows anyway. Knowing the right call and carrying it out cleanly under pressure turn out to be two separate skills, and Mind Stack scores both.
Tips to Improve Your Score
- When unsure, don't tap. A missed good item is cheaper than a wrongly dropped bad one — default to restraint.
- Aim matters as much as timing. A fast tap that lands off-centre narrows your tower even on a correct call. Slow down just enough to land it clean.
- Check your stability meter, not just your last drop. A run of near-misses can wear it down with zero outright mistakes — glance at it periodically, not only after an error.
FAQ
How is this different from Colour Liar or Word Lock?
Those give you two competing answers and ask which one wins — that's Stroop-style conflict. Mind Stack asks a different question: should you respond at all? That's Go/No-Go, a distinct branch of inhibitory control.
Go/No-Go sounds like a made-up name. What is it really?
It's a real research term — Go/No-Go is one of the standard tools for measuring response inhibition in both cognitive psychology and clinical research.
Why does a correctly-timed tap still sometimes narrow the tower?
Because landing off-centre matters, not just whether you tapped at all. Real impulse control isn't just deciding correctly — executing that decision precisely under pressure is a separate part of the skill, and this game scores both.
What actually ends a run?
Two ways: the stability meter empties, or the tower gets too thin to hold another block. Either one ends the session on the spot — there's no countdown ticking in the background.
