Every block has its own exit
Skwizzo Block Jam is a sliding block puzzle: each piece is dragged towards the edge of the board and leaves the grid only through the exit of its own colour. The path is almost always obstructed by other blocks, which in turn have to be moved, and the correct sequence must be worked out before time runs out. The screenshot shows level 350: coloured exits along the frame, a numbered block of ice, the timer at the top and a piece leaving the board.

22 mechanics, introduced one at a time
The first thousand levels introduce one-way blocks, ice to be melted, layers to be removed, locks and keys, ropes to be cut with scissors, time bombs, linked blocks, coloured gates, gates to be opened and star exits. From level 1001, eleven more are added: pressure pads and bars, expiring exits, paint, vortexes, chameleon blocks, traffic-light exits, boulders, colour combinations, fog, arrows and conveyor belts. Each new element is introduced separately. At level 1821, shown in the image, scissors, numbered layers, cracked slabs and directional arrows share the same grid.

Four power-ups
Four aids are available when the grid becomes jammed. Freeze stops the clock for 10 seconds; Gem frees a block and gives it the colour of an exit; Hammer destroys the selected block; Magnet removes every block of the chosen colour. Level 520, marked with a skull to indicate its higher difficulty, shows the Hammer and the Magnet in the foreground.

Perfect Move
A mode without a timer, in which the level must be completed without exceeding the number of moves of the solution calculated by the computer. A move counter replaces the clock, here showing eighteen. One move too many and the game displays the optimal solution; on success the reward is doubled. The mode unlocks as the player progresses through the Adventure.

Chaos
A run of 10 phases, extending to as many as 30 if the wins continue. Before each phase the player chooses a card, drawn from a deck of 120, that modifies the rules: faster-running time, darkness, fog, a field that shakes or flips upside down, frozen exits. At the start of the first phase, the screenshot offers six cards, including Crystal, Undertow and Wink, each with its own effect. The loot is awarded at the end of the run.

Replay and 3D field
The best run of each level is saved as a replay and can be watched again like a video, with pause and speed controls, including the camera movements made. With two fingers the field can be rotated, tilted and zoomed in order to view it from every side. At level 1150 the tilted view highlights keys, chained padlocks, scissors and a bomb with its countdown.

3D skins
Six skins for the blocks, from Classic to Nebula, each with its own sounds, and six skins for each power-up. The store allows them to be viewed in 3D before choosing. The screenshot shows the Power-ups tab with the Hammer in its Flame version; the other tabs are Blocks and Frames, and the Power-ups tab covers Freeze, Gem, Hammer and Magnet.

2000 levels, four modes
The game has 2000 levels: it starts with a few pieces and a single move and builds up to full boards, where one mistake can close the only valid path. Every level has been solved by the in-house solver and calibrated on its actual solution, and the record is saved on the map. On first launch the player chooses a path: Beginner, from level 1, with the mechanics introduced one at a time, or Veteran, from level 300. The main menu offers Adventure and a Modes button, which brings together Perfect Move, Random and Chaos; Random offers a surprise level without affecting progress in the Adventure. Lives refill over time; with Google Play Games, progress and purchases follow the player to a new phone, and no account is required. Purchases, namely coins, power-ups and bundles, are optional: everything else is unlocked by playing. The game is available on Google Play for Android and will be released on iOS.
