Slot Extreme, Crash Zap and Roulette SpeedBoost
Three titles that returning accounts open most often on 678k are Slot Extreme, Crash Zap and Roulette SpeedBoost. Slot Extreme is a reel slot with a bonus round that triggers from a scatter combination — RTP is shown on the game info panel where the provider exposes it, not as a number we publish separately.
-
Slot Extreme
A reel slot from the 678k lobby with a bonus round triggered by scatter combinations. Reel count, pay lines and RTP are displayed on the game's own information panel where the studio exposes them. Load it from the slots tab — it renders on a vertical mobile screen without horizontal scrolling.
-
Crash Zap
A multiplier crash game where a rising curve sets the round result. You decide when to exit — the multiplier at your exit point is applied to your stake, and the amount is added straight to your account wallet. Each round is short, making it a good fit for sessions on a mobile screen between other tasks.
-
Roulette SpeedBoost
A live dealer roulette format with a compressed betting window, streamed to a vertical mobile layout. The dealer manages the wheel; you place bets in the on-screen grid before the window closes. Results show on screen immediately, and any prize from a winning number is credited to your wallet at round end.

Slots, Live Casino Tables and Sportsbook in One Screen
The lobby organises everything into three tabs: slots, live casino and sports. Slots from Habanero, PG Soft, Spadegaming, JDB and PlayStar load directly without a secondary download step. Live casino tables and the sportsbook — including cricket markets covering international fixtures and BPL rounds — sit in their own tabs so you can switch without leaving the page.

678k lobby studios
The 678k lobby carries content from Habanero, PG Soft, Spadegaming, JDB and PlayStar. Habanero and Spadegaming bring reel slots with scatter-triggered bonus rounds. PG Soft and JDB cover both slots and arcade-style titles suited to short mobile sessions. PlayStar rounds out the catalogue with additional slot formats. To check the rules or features of a specific game, open that game card or the published information panel.

The Lobby on a Phone Screen — How It Sits on Home
On a phone-sized screen, the 678k home page is arranged for vertical scrolling rather than side-to-side navigation. The payment chip row — showing Nagad, Upay, bKash and Bank Transfer — appears in a horizontal swipe rail near the top of the home screen so you can check your active deposit route without scrolling past the game tiles.
-
Swipe Rail Payments
The Nagad, Upay, bKash and Bank Transfer chips sit in a horizontal rail at the top of the home screen. Swipe the rail to see all options without scrolling the page. Tap any chip to jump directly to that payment route inside the cashier — your account tier and route eligibility are shown at that point.
-
Pinned Cashier Button
The cashier button stays fixed in the bottom navigation bar across every page in the lobby. You do not need to scroll back to the top of the home screen to deposit — tap the cashier icon from anywhere, select Nagad or Upay, and the deposit flow opens as an overlay without navigating away from the game you were viewing.
-
Position-Preserved Back Navigation
Opening a game from the lobby and pressing back returns you to the same scroll position in the lobby, not the top of the page. This matters when you are browsing a long slot catalogue — your place is preserved. The same behaviour applies when returning from the cashier overlay after a Nagad or Upay deposit.
