SparkStack

SparkStack is a tile stacking puzzle game about clean lines and well-timed
combos. Drop one tile at a time into five columns, match three of a kind on top
of a stack to clear them, and chain your clears together to drive the score
multiplier up. Every round is short, nothing is timed, and the whole game works
offline — it is built for the few minutes you have, not the hour you do not.

You play on a five-column board that holds six tiles per column. A single tile
waits in the dock at the bottom of the screen. Tap a column to drop it there, or
drag it onto the board if you prefer to aim. Only the run at the top of a column
counts: get three matching tiles stacked on top of each other and they clear
instantly, scoring fifty points per tile. Clear again on your very next move and
the multiplier climbs — x1 becomes x2, x2 becomes x3 — so setting up two columns
to clear back to back is worth far more than clearing them one at a time. Fill
every column to the top and the round is over, so space management matters as
much as matching.

KEY FEATURES
✓ Endless free play — no timer, no lives, no waiting. Start a board and stop
whenever you like.
✓ 40 handcrafted levels — each with its own score target, move budget and coin
reward, tightening as you climb.
✓ A daily puzzle — one fixed challenge a day, 1400 points in 18 moves, with a
streak that grows every consecutive day you solve it.
✓ Combo multiplier up to x12 — consecutive clears compound, so the highest
scores come from planning two moves ahead, not from speed.
✓ A tile collection — five tiles across Common, Rare and Epic. Clear a tile type
for the first time and it unlocks in your collection with its own card.
✓ Coins that carry across every mode — earned from clears, level wins and daily
completions, and tracked on your home screen.
✓ A built-in tutorial — a four-step walkthrough plus first-run coach marks that
point at the board, the dock and the combo counter as you play.
✓ Fully offline — no account, no sign-in, no network connection needed at any
point.

HOW IT WORKS
1. Open the app and tap Play for a free board, or pick a level from the grid.
2. Tap a column to drop the tile waiting in the dock, or drag it where you want.
3. Land three of the same tile on top of a stack and watch the run clear.
4. Clear again on the next move to push the multiplier higher.
5. Come back tomorrow for the daily puzzle and keep your streak alive.

WHY SPARKSTACK
The rules fit in one sentence and the depth comes from where you put things.
There are no power-ups to buy, no energy meter counting down, no advertisement
between rounds and no account to create. Progress is stored on your device and
nowhere else. The whole game is a single download that works on a plane, on the
underground, or anywhere the signal drops — and a round takes as long as you
want it to, because nothing on screen is racing you.
