Frequently asked questions

What is HIDDEN BLOCKS?
HIDDEN BLOCKS is a free spatial brain puzzle by LOGAN LAND. You count cubes stacked into 3D shapes, including the blocks tucked away behind the ones you can see, to train your sense of space.
What game modes does it have?
Two core modes. Count All asks you to count the whole stack including every hidden block; Count Hidden asks you to count only the blocks completely hidden behind others. There is also a Daily Blocks challenge each day.
Is it free to play?
Yes. HIDDEN BLOCKS is free to download and play on Android and iOS, with optional in-app purchases.
How do you count hidden blocks?
Every block sits on something — there are no floating gaps — so you can infer the columns you can't see directly. Picture the full 3D shape, work out each column's height, then count the blocks covered on all visible sides.
What platforms can I play on?
HIDDEN BLOCKS is available on Google Play (Android) and the Apple App Store (iOS). In Korea, you can also play it inside the Toss app (Apps in Toss).
Who made HIDDEN BLOCKS?
HIDDEN BLOCKS is made by LOGAN LAND, an independent game publisher. For support, contact support@loganland.app.
What's the difference between Count All and Count Hidden?
Count All is the total number of cubes in the stack, including the ones hidden behind others. Count Hidden is only the cubes completely hidden from view. Same stack, two different answers.
What is Daily Blocks?
Daily Blocks is a fresh puzzle every day. Solve it to earn a reward, then come back tomorrow for a new one — a quick daily brain workout.
Do I need an account to play?
