What is Stella Orbs?

Stella Orbs combines a falling-block puzzle with a party battle. Pieces of three orbs in five elements (fire, water, grass, light and dark) drop onto a honeycomb board of hexagonal cells. Connect 6 or more orbs of one colour to clear them, and the clear becomes damage that chips away at the enemy at the top of the screen.

Each enemy has a countdown that ticks down every time you place a piece. At zero it strikes back at your party or drops junk orbs onto your board. Clearing the board cleverly and choosing which character goes in which slot both decide the fight.

The world: spirits of the constellations

Your allies are 75 spirits borrowed from Norse mythology, Arabian folklore, Japanese history, Hindu mythology, Greek mythology, Hawaiian mythology, Japanese mythology, Legends from around the world, Alchemical lore, Middle Eastern lore, Mesopotamian mythology, Japanese folklore, Arthurian legend, Chinese mythology, Celtic mythology, Egyptian mythology, French history, Christian tradition and Japanese legend. 75 of them (Loki, Ifrit, Oda Nobunaga, Agni, Prometheus, Pele, Kagutsuchi, Phoenix, Surtr, Chimera, Salamander, Izanagi, Poseidon, Susanoo, Leviathan, Varuna, Jormungandr, Enki, Ryujin, Tiamat, Triton, Undine, Demeter, Pan, Merlin, Idunn, Gaia, Shennong, Dionysus, Persephone, Cernunnos, Centaur, Dryad, Amaterasu, Zeus, King Arthur, Apollo, Athena, Ra, Joan of Arc, Artemis, Astraea, Valkyrie, Pegasus, Lucifer, Hades, Ereshkigal, Nyx, Izanami, Fenrir, Shiva, Osiris, Anubis, Hel, Cerberus, Takeda Shingen, Tamamo-no-Mae, Sekhmet, Fafnir, Hijikata Toshizo, Genbu, Aphrodite, Siren, Xiwangmu, Nuwa, Freyja, Gnome, Uesugi Kenshin, Byakko, Thor, Sylph, Tsukuyomi, Odin, Hecate, Chang'e) already have finished artwork, shown in star-lit costumes. Each carries the power of one of the five elements, and the stories and attributes of the myths are reflected in the names and effects of their skills and ultimates.

The adventure runs through 15 chapters and 75 stages ("Starsea Corridor", "Temple of Constellations", "Celestial Sphere at Dusk", "World Tree of the Frost Night", "Thundering Olympus", "Underworld of Seven Gates", "Star River of the East", "Kingdoms of Sand and Great Rivers", "Land of Wildfire and Storm", "Forest of Moon and Vine", "The Holy Sword and the First Night", "Warring States Under the Moon", "Peach Garden of the Heavens", "Land of Gold and Frost", "The Edge of the Starsea"). Some stages end with one of the playable spirits standing in your way as the boss. Beyond the main stages there are Special Dungeons for farming materials and coins, and a Daily Challenge you can try every day.

Key features

A party of three, and shapes are attacks: you place characters in the Ring, Pyramid and Line slots. Build the matching shape from 6 orbs of one colour and every orb of that colour on the board disappears, while the character in that slot attacks and fires a skill.
Chains scale the damage: if the orbs that fall after a clear make another clear, a multiplier is applied once at the end to all the attack and healing of that turn: ×1, ×1.5, ×2.25, ×3.38 and beyond.
Healing colours: exactly four colours of orbs fall, always. Clearing orbs of a colour nobody in your party has restores HP.
Five-element affinity: fire beats grass, grass beats water, water beats fire, and light and dark beat each other. An advantage deals ×1.75 damage and a disadvantage ×0.5.
Ultimate Skills (ULT) and leader skills: clearing orbs of a character's element charges its ultimate gauge, and you tap the icon to fire it when full. The leader (the Ring slot) also has a leader skill that works for the whole battle (more party HP, stronger damage for an element, orbs of its own colour appearing more often, and so on).
Growth and collecting: characters grow stronger as they level up, with a level cap of 30 for ★3 and ★4 and 50 for ★5. Recruit new allies with the gacha, and collect materials and coins from the login bonus and daily missions.
Phone or PC: it runs entirely in the browser, with taps and swipes on a phone or the keyboard on a PC.

Screens and artwork

These are the 75 characters, all with finished artwork (the Characters page introduces every one of them).

The lobby screen: a carousel of the party characters, the sortie button and the menu tabs at the bottom — The lobby (screen example). The three party members rotate in a carousel, and the sortie button at the bottom starts a stage.

A battle screen: the enemy with its HP bar and countdown at the top, the honeycomb board with stacked orbs and the next piece in the middle, and the party HP and three gauges at the bottom — A battle (screen example). You clear orbs to attack the enemy and track ultimates with the gauges at the bottom.
