Choosing a bonus through Scatters
Three distinct entry counts
Power of Ten assigns a separate bonus to each qualifying FS Scatter count. Three symbols lead to Deck of Fortune, four to Whopping Wheels and five to the hidden On the House mode. The board result therefore selects a ruleset rather than simply increasing one free-spin total.
The feature names also identify different goals. Deck emphasises more frequent Wheels, Whopping Wheels collects sticky prizes through refilling lives, and On the House guarantees Wheel coverage across all reels.

Deck of Fortune
Deck of Fortune starts with 10 free spins after three FS symbols land together. Base-game mechanics remain active, but the chance of Power Wheels increases. Landed Wheels continue to wait for line wins before revealing their Cash Prizes.
Additional FS symbols extend the feature. Two at the same time add two free spins; three add four. These extensions preserve the Deck mechanics and create more opportunities for Wheel activation.

Whopping Wheels lives
Four FS symbols activate Whopping Wheels with three lives represented as free spins. Whenever a Power Wheel lands, all lives refill and that Wheel becomes sticky. It stays inactive in the same position while the collection continues.
Regular wins are still paid after each spin. The stored Wheels form a delayed feature layer, waiting until the last life is gone. This makes grid occupancy and life management more important than a fixed spin total.
Final Wheel activation
After the last Whopping Wheels life is consumed, every sticky Wheel activates. The revealed numerical values are added and applied to the bet under the standard Wheel rule. A MAX WIN result immediately reaches the 10,000x limit.
A full grid ends the bonus before the remaining life count reaches zero. All positions are already occupied, so the game proceeds directly to combined activation. The filled board acts as an alternative completion condition.

Hidden On the House
Five FS symbols open On the House with 10 free spins. The bonus uses Deck of Fortune rules but guarantees at least one Power Wheel on every reel on every spin. All five columns therefore receive Wheel presence throughout the feature.
Two additional FS symbols add two spins, and three add four. Every extension continues with the same guaranteed Wheel condition, increasing the number of spins in which all reels contain feature potential.

Bonus counters on mobile
Deck and On the House need visible free-spin counters, while Whopping Wheels needs a refilling-life indicator and sticky positions. A responsive interface can place these elements around the five-reel grid without changing its dimensions.
The official mobile page confirms a single-column presentation for narrow screens. Large headings and isolated content blocks make the three trigger counts easy to compare, while the game preserves the published Wheel rules.
