Gameplay on a Schoolyard level: glass marbles in five chalk-drawn columns.

How a move works

Each board has a highlighted middle row. Drag a column up or down, or drag the middle row sideways, by one space. When three or more marbles of one colour sit side by side in the middle row, they clear and make room for the next ones.

Match four or more to leave a special marble: Water, Fire, Dynamite or Rainbow. Each planet brings its own obstacles, such as colour lockers, pearl shells, ice and hot anvils.

Animation: dragging the middle column down by one space brings a blue marble into the middle row, next to two other blues. The three blues clear.

What's in the game

Campaign: 200 levels on 10 planets

Every planet has its own hero, look and obstacles. A level gives you a set number of moves or a time limit; finish it to earn stars and XP that raise your player rank.

In timed levels, quick clears in a row raise a points multiplier up to ×5.

Marathon: no move limit

Finish all 20 levels of a planet to open its Marathon. New marbles keep arriving, faster over time, until the board fills up. The board grows to six and then seven columns as your score climbs.

Your best score of the week goes on that planet's leaderboard, and the top three win coins when the week ends. The first Marathon start each day on each planet is free.

Races in the Triumph System

Three race planets have their own Triumph System on the space map. It opens after the first 60 levels. Meadow Rally is open from the start; Canyon Challenge and Orbital Masters need player rank 24 and 32.

Six players get the same boards and powers. Meadow Rally and Canyon Challenge have five boards ranked by time and moves; Orbital Masters is one 60-second score round. Entry is 50, 200 or 500 coins and the podium shares the prize pool. Practice is free. Empty places may be filled by computer-controlled opponents.

Duel

Google Play: version 1.0.36. App Store: version 1.0.36.

A head-to-head match on five columns. Your clears send extra marbles to your rival's board, and a charged Heat meter lets you throw an obstacle at them. Each of your five powers can be used once.

A duel costs 100 coins. A win pays 180 coins and 30 XP once the server confirms the result; a loss, forfeit or quit costs the entry and one life. A draw refunds the entry.

Duel opponents may be computer-controlled and are matched to your results.

Google Play: version 1.0.36. App Store: version 1.0.36.

Your planet

After the first 60 levels you can create a planet of your own. Build a house, workshops and decorations from plans you uncover in levels, and hire a team to speed up production.

Choose the ground under each building, join nearby ponds into one lake and set the challenge for visitors.

Eternal Night

A Halloween adventure in its own system on the space map: 30 stages across Pumpkin Valley, Whispering Forest and Midnight Castle, with pumpkin bombs, bats, ghosts and other obstacles of its own.

Light the three Great Lanterns and collect decorations for your planet. Its XP counts toward your main rank, and the adventure stays in the game after Halloween. Open it with the pumpkin button on the main screen.
