Is it actually free?
Yes, all of it. Nothing to install, nothing to buy, no ads in the arena. Play as a guest right now; signing in only puts your runs on the leaderboard.
Do I need to download anything?
No. Open the page and you're in, usually inside ten seconds. It runs on desktop and on a decent phone or tablet.
What's the difference between the two boards?
Ring Maze is the built one: a hexagon of hedge walls with doorways that widen every five waves, and you build in the plots beside the corridors. Open Field is bare ground - your towers are the walls, so the route is whatever you leave open. Same towers, same monsters, totally different puzzle. You pick one on the join screen.
How many towers are there?
180, across 36 upgrade lines - twenty-four single-element lines that go six tiers deep, plus twelve fusion lines that mix two elements. The top tiers of every line ascend, welding a second and even a third element into one turret.
What are the six elements?
Fire, air, earth, poison, water and arcane, on one wheel where every element beats the next two. Strong hits land for double damage, weak ones for less than half - and the deeper the run goes, the harsher the wheel gets.
Can monsters get past my maze?
Some try. Flyers soar straight over your walls, jumpers hop them a limited number of times, and raiders shoot back at your towers and camps. Not every tower can hit every body - big slow slammers can't reach flyers, slow snipers can't track jumpers - so a real defense mixes roles.
Can I play with friends?
Up to four of you. Co-op puts everyone on one board sharing one pool of lives. Versus gives each player their own board and the same waves - everything you kill gets sent onto theirs, and three sabotage abilities exist only in that mode.
How does a run end?
It doesn't, until you do. Waves scale forever and there is no final boss. Your score is the wave you reached when the last life walked out the gate.
Do I have to unlock towers every run?
Four lines are open from the first second. The rest get earned during the run by playing their element - going wide opens new lines, going deep opens higher tiers. Abilities are researched with what you mine and forge.
Does it work on a phone?
Yes, and the interface rebuilds itself for it: the build menu becomes a bottom sheet you thumb through, and tapping a tower opens a ring of actions right around it instead of a side panel. Same game, same board, nothing cut.
