Small rules.
Surprisingly big decisions.
Learn the whole idea before your coffee cools. Getting good takes a little longer.
Read the space
A huge opening is tempting, but corners and narrow gaps matter too. Compare the numbered openings above: the center is not automatically the biggest move.
Beat the clock
When the timer runs out, the player covering more area wins. Watch the percentages, react to powerups, and make every remaining move count.
Start with easy AI to learn the timing. Then try different boards and filler shapes, or switch to simultaneous rounds where both placements resolve together. The complete rules explain growth, timers, and scoring.
Play your way.
A solo break, a shared screen, or a quick duel from opposite sides of town.

Do I need to install an app?
No. fill.zone plays in a web browser. Open the game on a phone, tablet, or computer with JavaScript enabled, then choose a mode.
Can I play without an account?
Yes. Solo and local games work as a guest, and guest online matches are casual. Signing in is optional; competitive ranked online matches require both players to be signed in.
Is every match thirty seconds?
A standard match lasts thirty seconds after the starting countdown. Placement timers keep the action moving. The preview on this page is a short demonstration, without a match clock.
Can I use a mouse instead of a touchscreen?
Yes. Click a valid opening with a mouse or tap it on a touchscreen. The objective and placement rules are the same.
How is this different from a drawing game?
You choose a point rather than drawing a line. The game grows a circle, square, or triangle into the available space. The challenge is judging how much territory each point can claim.
Thirty seconds.
