About this game

Clear the board. Clear your mind.



Glowline Zen is a relaxing puzzle game for anyone who wants to
unwind.
Every glowing arrow can fly off the board only in the
direction it points, and only if nothing blocks its path to the edge.
Tap them in the right order and watch the whole board melt away. It is
a calm neon logic puzzle you can play anywhere, on the sofa or on the
last train home.

No timers unless you ask for them. No energy meters. No pressure.

Every puzzle hides a picture


From level 11, each board conceals a hidden silhouette. As you clear
the arrows it slowly emerges, then ignites in neon when you finish.
There are 190 to discover, and every one you earn joins your gallery.
A quiet reward for a quiet game.

A new puzzle every day


Daily Zen gives you one fresh board each day, the same puzzle for
every player worldwide. Keep your streak going at your own pace. Miss
a day and nothing scolds you, because this is a game about calm, not
guilt.

Finish all 200 handcrafted levels and you unlock Zen Flow, an endless
mode that generates new geometric boards forever. Prefer a challenge?
An optional Time Trial mode tracks your best times. It stays off
unless you turn it on.

Stuck? Help is built in


Use a Hint to light up a fireable arrow, an Eraser to
remove one that is in the way, a Magic Wand to fire everything
that can currently move, or the Grid Ruler to flash guide lines
across the board. Solve at whatever pace feels good.

Buy it once or never, the puzzles are the same either way.
