DUAL ELEMENTS RUN

The Golem has awakened. Run along the root trails, switch lanes, jump, slide and swap between fire and water before it catches you. An endless 3D runner in the style of mobile runners.

  • 3 lanes
  • 20 worlds
  • 90° turns
  • Daily challenges
Play now Opens instantly, on your phone or computer.
Running
Swipe sideways to change lanes, up to jump, down to slide. On a keyboard, use the arrow keys or WASD.
Elements
Lava does not burn Ignis, but puts out Aqua. Water does not affect Aqua, but puts out Ignis. Tap TROCAR (“swap”, or E) to become the other element, or jump over the puddle.
Obstacles
Low roots: jump. Hanging signs: slide. Low walls and stone carts: change lanes or take the ramp. Carts with green eyes come straight at you.
The Golem
It is always right behind you. Bumping sideways makes you stumble: it roars, the screen edges turn red and you can hear a heartbeat. Stumbling again during that time ends the run.
Crystals and Fury
The golden ones are your money in the shop. The ones in your character’s color (with Ignis, with Aqua) fill the Elemental Fury bar: when it is full, you destroy everything for a few seconds.
Power-ups and shop
On the track: Magnet, Shield, ×2 and Cloud, which carries you through the air. In the shop, each power-up has 5 levels, and you can buy starting items such as the Head Start.
Worlds
20 worlds take turns every 500 m, and many change the rules: fog, icy ground, low gravity, rocks falling from the sky, running underwater, double points and more. Colors, scenery and music change in each one.
Turns
At the end of each world the track ends in a T, like in Temple Run: swipe to the right side and discover the next world. After the 20th, a new lap begins, with the worlds in a different order and points worth more.
Missions and ranking
Complete the 3 missions of each set to raise your points multiplier, plus the 3 new challenges every day, which pay golden crystals. Died? Spend golden crystals to continue where you left off. Your best score from a single run goes into the online ranking, and it only asks for a nickname.
Run menu, with Ignis and Aqua to choose from

DUAL ELEMENTS RUSH

Roots have trapped Ignis and Aqua. Lead the elemental army through 20 worlds and 200 levels, choose the right gates, gather crystals and break the chain. The army walks and shoots on its own: you only drag your finger.

  • 200 levels
  • 20 worlds
  • 20 bosses
  • Shop and power-ups
Play now Opens instantly, on your phone or computer.
Army
Drag your finger sideways (or use ← →). The army advances and shoots on its own, and its size is its life: the bigger it is, the more of the track it sweeps.
Gates
Green gates add and multiply, red ones take away. Swap gates turn the army from fire to water, or the other way around. Sometimes the math asks you to choose between switching element or gaining soldiers.
Walls
Ice melts fast against fire. Lava goes out fast against water. Roots resist both equally. Arriving with the wrong element is costly.
Crystals
The ones in your element’s color are worth 2 (with Ignis, with Aqua) and the golden one is worth 8. The army collects everything inside the circle it occupies. Chests give soldiers and scatter crystals when you shoot them open.
Bonus stairs
At the end of the level the army climbs on its own. Each step costs a few soldiers and raises the crystal multiplier. Arrive with a big army to climb higher.
Power-ups
On-screen buttons: Burst, Magnet, Shield and Swap (on a computer, keys 1 to 4). You start with 3 of each and buy more in the shop.
Worlds
20 worlds of 10 levels, each ending with a boss. Every world has its own scenery, walls and boss, and the difficulty rises gradually. The worlds run from the Caldera, the first, to the Lantern Festival, where the last chain lies.
Shop and ranking
Starting army, firepower, fire rate and crystal magnet, with 10 levels each. Lost the level? You keep half of the crystals. The sum of your best score in each level goes into the online ranking.

DUAL ELEMENTS .io

Team Fire against Team Water in a multiplayer arena. Collect the crystals of your element, grow and wipe out the rival team, playing with other people in real time. Opens in your browser, on a computer or a phone.

  • 15 per room
  • 20 maps
  • Real time
  • Online ranking
Play now Play instantly, in your browser. It only asks for a nickname.
Online
Everyone in the same arena, in real time. You join a room with real players; when people are missing, bots fill the room up to 15 characters.
Ranking
The start screen shows the players with the highest scores in the arena. Real people only: bots do not make the list. During a match, a panel shows the players of both teams.
Crystals
Each character only collects the crystal of its own element (2 points). The golden crystal is worth 8 and anyone can take it.
Hunting
Fire only destroys Water and Water only destroys Fire. Touched a rival with fewer points than you? They fall and you take their score. Teammates pass through each other.
Portals
They come in pairs of the same color. Once used, the pair closes for 2.5 seconds, so whoever is chasing you cannot follow.
Pits
Falling costs half of your score, and you respawn at another point of the arena.
Altars
They swap your element and, with it, your team (8-second cooldown). Use them to escape a chaser or to hunt smaller former teammates.
Maps
20 arena maps, each with pits, lava and water pools, portals and altars in different places. There is something for everyone: ice crevasses, swamp, a coral maze, a lightning zigzag, a garden of stars. You choose the map before you enter.
Controls
On a computer, use the mouse or WASD to move and Space to dash. On a phone, drag your finger and tap DASH. A dash costs 6% of your points.

RANKING

    Illustrative simulation of the rules: each character looks for the crystals of its element and hunts smaller rivals.

    Looking for online games to play with two? Dual Elements was born from a simple idea: fire and water need each other.

    Co-op games

    In Co-op mode, Ignis (fire) and Aqua (water) cross levels with lava, water, acid, boxes and levers, and only reach the door after collecting every crystal. Fire crosses lava, water crosses lakes, and each depends on the other. You can also play alone in Solo mode.

    Games for couples and for two players

    Two players, one computer, one character each. A great pick for couples, friends or parents and kids: no sign-up, no payment and nothing to install.

    Fire and water games

    The same rule applies across the whole series: fire puts out water and water puts out fire. Choosing the right element at the right moment decides the level, the run, the battle and the match.

    Free online games

    Four games that open right in your browser, on a computer or a phone: a co-op platformer, an endless runner, an elemental army game and an online multiplayer arena.

    Quick questions

    What almost everyone wants to know before playing.

    What are good online co-op games to play with two?

    Dual Elements is a cooperative platformer: one player controls Ignis (fire) and the other Aqua (water), on the same computer. Together they cross levels with lava, water and acid, collect every crystal and reach the door side by side. It is free and opens in your browser.

    Is there a free game for couples?

    Yes. The Co-op mode of Dual Elements was designed for two players on the same computer, so it works well as a couples’ game, and also for friends or parents and kids. No sign-up or payment is needed.

    Are the games free?

    Yes. All four games open for free in your browser, with nothing to install. The in-game shops use crystals you earn by playing, not real money.

    What are fire and water games?

    They are games in which two opposite elements have strengths and weaknesses: fire crosses lava but is put out by water, and water does the opposite. In the Dual Elements series this rule applies to all four games.

    Do I need to install anything?

    No. All four games open right in your browser. On a phone, if you like, you can create a Dual Elements shortcut on your home screen: the Play button shows the step by step.

    Does it work on phones?

    Run, Rush and .io were made for touch screens and also play on a computer. Dual Elements works on a phone in Solo mode only; Co-op, for two players, is for computers. If you can, hold your phone horizontally in Dual Elements.

    In which languages can I play?

    Dual Elements, the first game, has six languages: Portuguese, English, German, Chinese, Spanish and French, and you switch inside the game itself. This site is also available in those six languages, through the bar at the top of the page. For now, Run, Rush and .io are in Portuguese.

    How long does each game last?

    Dual Elements has 10 levels in Solo and 10 in Co-op. Run is an endless race, with 20 worlds to discover. Rush has 20 worlds of 10 levels, that is, 200 levels and 20 bosses. .io has 20 arena maps, in short rounds.

    Is my progress saved?

    Yes, in the browser of the device where you played: levels, crystals, shop upgrades and records. Clearing the site data in the browser erases the progress, and it does not move on its own from one device to another.

    How does the ranking work?

    There is no sign-up or email: you only pick a nickname. The ranking is online and each game has its own: best score in a run in Run, sum of your best levels in Rush, top arena scores in .io and a completed campaign in Dual Elements.

    Are the games from the same series?

    Yes. The characters are the same, Ignis and Aqua, and the same rule applies: fire puts out water and water puts out fire, so choosing the right element at the right moment decides the match.
