About this Slot
ASTRA is a space-themed slot from Cloud with an RTP of 96.69%, high volatility and a maximum win of 20,000x. The game uses a 7x7 grid with Cluster Pays mechanics, where five or more matching symbols connected horizontally or vertically form a winning cluster. Diagonal connections do not create wins.
Cascading reels drop new symbols into empty spaces after each winning cluster is removed, and cascades continue until no new wins form. During cascades, cell multipliers build from 2x up to 1,024x, applying to subsequent wins in that cascade.
Three scatter symbols trigger a minimum of eight free spins. Additional scatter symbols landing during the opening cascades of the base game upgrade this feature, increasing the starting free spins count. During free spins, each new scatter symbol that lands adds one extra spin to the round. Cell multipliers persist and continue to grow throughout the free spins round.
The game offers five bonus buy options at different stake levels. ANTE costs 10x bet and guarantees a scatter symbol on the first reel. BONUS costs 100x bet and provides access to a feature path. SUPER costs 300x bet with its own feature path. MYSTERY costs 500x bet offering a different route to the bonus mechanics. EXTRA costs 1,000x bet and raises the stake significantly. Starting multipliers in the bonus round depend on which tier is reached through these buy options.
