Money Cart 2

Money Cart 2 by Relaxgaming is a video slot designed around the Hold & Win / Bonus Reels mechanic, dispensing with a traditional base game so every spin gives you a chance at the bonus feature. The game uses a 5-reel, 4-row layout that can expand by unlocking up to two extra reels during the bonus round. Its theme channels a gritty, steampunk-Wild West train heist vibe, complete with characters like the Payer, Collector, Sniper, Necromancer, and their persistent versions. To trigger the bonus round players need to land at least three bonus symbols, which then lock and award three respins. Each new symbol that lands during the bonus resets the respin counter back to three.

There are special symbols with unique effects: the Payer adds its value to all other visible symbols; the Collector gathers values of other symbols into itself; a combined Collector/Payer both collects and then shares its total with other symbols. Other modifiers like Reset Plus increase the respin count, while persistent versions of Payer, Sniper or Collector remain active across subsequent spins once they land. Golden bonus symbols show higher coin values than standard bonus symbols. The bonus round ends when the respin counter runs out, all reel positions are filled, or the maximum win is reached, with a special reward when the full grid is occupied. Maximum potential wins are capped at 5,000× your stake.

You can play it for real money.
