Block Puzzle Den

Block Puzzle Den is a block-fitting puzzle with one promise the genre has never
made: the pieces always fit.

Every set of three you are dealt is checked by a solver before it reaches you.
Not "usually solvable" — verified, every single time. If you lose, it is because
of where you put things, not because the game quietly handed you an impossible
hand.

FIVE WAYS TO PLAY
• Endless — drag pieces onto the board, fill a row or column to clear it, and
build a streak. Miss one and you drop a single tier, never the whole run.
• Daily — one puzzle a day, the same for everyone, seeded from the date.
• Gravity — pieces fall to the floor as you place them. The board becomes
terrain you are building on, not a grid you are filling.
• Chain — polyomino pieces fall and you steer them. Three of a colour in any
direction clears, then everything drops and checks again, so cascades happen.
Runs of four and five leave specials behind.
• Adventure — 100 levels, each with its own objective. Every one of them was
proven solvable by a bot before it shipped.

FREE, AND ACTUALLY FREE
No ads. Not one banner, no full-screen interruption, no rewarded video. Nothing
to buy — no coins, no lives, no "remove ads" upgrade. There is no shop, because
there is nothing in it.

It also works completely offline. The game makes no network requests at all,
and everything you do stays on your device.

A FREE HINT, HONESTLY LABELLED
Stuck runs get a hint that marks a placement — it never plays the move for you.
Runs where you used one are labelled Assisted, and your Clean best is tracked
separately, so the number you are proud of stays the number you earned.

No timers. No lives. Nothing expires while you are not playing.
