Six columns, five rows. Eight or more matching products anywhere on the grid form a win. Each product group pays once. All winning products disappear together; remaining symbols drop and new ones fill from above.
Turn up the Rush
The first winning cascade uses ×1, the next ×2, then ×3 and ×5. Further cascades stay at ×5. Apply the current multiplier once to each group payout. Rush resets at the end of the cascade chain.
Coupon Wild
The host can cast one Coupon Wild before the opening grid is evaluated. It substitutes for products, never Gift Scatters. It joins one group that provides the largest increase in total payout; ties go to the first product in the paytable. Wilds are never counted in multiple wins. An all-Wild field pays as Watches. Tapping the host is a visual reaction and does not create a Wild.
Doorbuster
Three or more Gift Scatters on the opening grid unlock Doorbuster after the cascade chain. Gifts arriving in refills do not trigger another bonus. Start with three prize boxes and three delivery attempts. New boxes and bags lock and restore all three attempts; each empty delivery consumes one.
A newly landed Rush Bag collects every uncollected box, stores their sum and clears their cells. Previously stored bag totals are never collected again. Multiple new bags resolve from the leftmost column top-to-bottom, then the next column. The first collects the boxes; any later bag in the same delivery stores zero. The bonus ends at zero attempts, a full grid after collection, or the round win limit. Final bonus win is all bag totals plus remaining boxes, counted once.
Base game and Doorbuster share a ×5,000 total round limit. Reaching it ends the whole round. Box and bag face values show their potential value; the final amount is limited by the remaining round budget. No further deliveries occur after the limit is reached.
Paytable
Multiples of the total bet, before Rush. Products ordered from lowest to highest value. Only Base mode is offered; one round costs one bet. Doorbuster is included in the triggering round with no additional bet.
Doorbuster box values: times the triggering bet. Doorbuster keeps that bet throughout the feature.
Theoretical RTP: 96.00%. Maximum win: ×5,000. Non-zero win frequency: 35%. Doorbuster frequency: approximately 1 in 60 rounds. Maximum-win frequency: 1 in 5,000,000 rounds. Each new round is independent; Rush does not carry between bets.
Local preview uses virtual credits. The displayed RTP describes long-term outcomes, not the result of an individual session. Turbo, sounds and host reactions never change an outcome.
Settings
Sound is on by default. The music note button turns music, ambience and effects off or on, and your choice is remembered. Audio starts after your first interaction with a control. Turbo shortens the animation. Space starts a round; during presentation it requests Stop. Autoplay runs the selected number of rounds and stops when Doorbuster triggers, when the balance is too low for another round, when a connection or round error occurs, when the page is hidden, when rules are opened, or when its separate square button is pressed. Stopping autoplay allows the current round to finish; a connection error may require reconnecting to complete it.
Controls
SPIN starts one round. During presentation it becomes STOP, which quickly finishes the current animations. Anticipation finishes at its normal speed, then the Stop request resumes. Stop resets before each bonus delivery and never starts another round or changes the recorded outcome. Minus and plus change the bet; the amount selector offers all available server bet levels. A opens autoplay choices; selecting a count confirms autoplay. During autoplay, A becomes a separate square button that stops autoplay after the current round. The main STOP button only accelerates the current round and keeps autoplay running. The lightning button changes speed, the music note controls sound, and i opens rules. Space starts a round or requests Stop while animations are playing. Reduced motion limits movement. Tapping the host plays a visual reaction. Available controls respect the session's jurisdiction settings.
Choose 10, 25 or 50 rounds in the autoplay window to confirm and start that sequence. The × button closes the rules or autoplay window; closing autoplay without choosing a count starts no rounds. Escape also closes these windows. Bonus and win announcements advance automatically after three visible seconds and have no confirmation button.
Connection and unfinished rounds
RETRY reloads the page after a loading error. RECONNECT reloads and checks the server session after an interrupted request; it does not repeat the previous play request. If an unfinished round is found, CONTINUE presents and completes that recorded round without placing another bet. Its original bet remains selected after completion. If the server no longer offers that amount, the result and original bet remain visible; choose a currently available amount before starting another round. No new bet is placed at an unavailable amount.
Replay controls
PLAY REPLAY starts the recorded round. After it finishes, PLAY AGAIN shows the same round again. STOP accelerates replay animations under the same anticipation rules. Replays never place bets or change a wallet balance; bet selection and autoplay are unavailable.
Malfunctions void all wins and plays. A stable internet connection is required. If disconnected, reload to finish an unfinished round. Expected return is calculated over many plays and does not predict a single session. The display is illustrative and does not represent a physical device. Winnings in Engine sessions are settled from the Remote Game Server response, never from browser animations. TM and © 2026 Engine.

Review features
In the local demo, Review features opens or closes the preview controls. Cascade review shows a cascade example, Coupon review shows a Wild example, and Doorbuster review shows a bonus example. Review rounds use a separate session and do not change your balance. Reset to 1,000 demo credits restores the local demo balance and clears the displayed result; it does not add funds to an Engine session. Review and reset controls are unavailable in Engine sessions and replays.
