15 Totem Stacks: Hold & Win

This new Penguin King slot revolves around the titular Totem symbols. On any spin, expanded Totems may enter the reels to trigger a Hold & Win bonus, where three retriggerable respins bolstered by sticky symbols unveil potentially impressive rewards.

The total number of Totems stuck to the grid at the end of a Hold & Win bonus determines final payouts. A minimum of six Totems is required for a guaranteed 3x prize, while 15 Totems trigger a 1,000x return.

Just five paylines are included in 15 Totem Stacks: Hold & Win. Players should look for fruit symbols, bells, sevens, and Wilds during base rounds for immediate wins.

3 Christmas Pyramids: Hold & Win

Players can get into the festive spirit early at one of the best sweepstakes casinos with 3 Christmas Pyramids: Hold & Win.

Set on a backdrop of snowflakes, snow-topped pyramids, and a dark desert night sky, this Penguin King slot offers opportunities to unwrap four special jackpots worth up to 1,000x.

Several special features enter the fray here, including 10x Coin Prize multipliers, a themed respins bonus, and an enhanced free spins boost.

Watch out for Christmas Trees, too, as these glimmering icons could trigger Collect, Mystery, or Double bonuses. A seasonal sticky-symbols-emblazoned Hold & Win bonus may activate alongside Christmas Trees, rounding out the main features in this Christmas-themed Egyptian slot.

3 Energy Diamonds: Hold & Win

With three glistening diamonds swirling across the top of the grid, this 5x3 sweepstakes game increases your chances of hitting five distinct jackpot prizes. These instant rewards offer 25x to 2,500x returns and may be activated during base rounds and the Hold & Win bonus.

The aforementioned Hold & Win round is the most valuable feature baked into 3 Energy Diamonds: Hold & Win — Coin Prizes are available only during the retriggerable sweepstakes casino bonus feature.

Increase, Collect, and Expand bonuses are tied to each of the game’s three swirling diamonds. When a Special Coin lands, any of the following features could create an augmented bonus experience:

Increase: Get an improved multiplier worth up to 50x.
Collect: Assemble all sticky symbol values on the grid.
Expand: Places a new row at the bottom of the grid.
