Stack Sprint 3D

A full-3D one-thumb block-stacking race with no buttons. Drag left and right anywhere to steer your runner across three lanes and scoop up coloured blocks that stack into a growing tower under your feet. Every gap in the track needs a set number of blocks to bridge, shown on a sign ahead, so arrive with enough or you plunge in and lose your whole stack. Striped walls knock blocks off, so slip through the opening, and multiplier gates either grow your tower or shrink it, so pick the green one. Gold blocks are worth three, and later levels add double gaps, sliding walls and narrow openings. At the finish the tower is cashed in on a ramp: every block you still hold shaves time off your result, so a tall tower can beat a faster runner. Three rivals race the same track. Twenty-five short levels carry you through candy, sunset, neon, ice and lava worlds. Finish in the top three for one star, second or better for two, and win for three. Beat level 25 to become Champion, then run endless tracks. The Daily Challenge and friend rooms use one fixed track for everyone and compare finish times.

How to play

Press and drag left or right anywhere to steer across the lanes and collect blocks.
Check the GAP NEED sign and arrive with at least that many blocks. Dodge walls and take the green gates.
Finish in the top three to pass. Tap the card for the next level, or tap again to retry straight away.

Tips

Blocks beat speed: a tall tower at the finish ramp is worth seconds, so do not rush past a full lane of blocks.
Keep a few spare blocks over the number on the gap sign, because a fall costs the whole tower and about two seconds.
Pick the green multiplier gate whenever you can, and send your tower through the wall opening rather than into the wall.
