Clover Strike: Hold and Win

Overview

Clover Strike: Hold and Win unleashes a burst of four-leaf clover energy, illuminating a swoony 3x4 grid with 10 paylines, feature-packed gameplay, and the chance to win one of four in-game jackpots. Delicious fruits appear on the reels alongside electric Bonus Clovers, high-voltage Strike Clovers, and ultra-powerful Strike Clovers Boost, all of which increase your winning potential.

The moment Strike or Strike Boost Clovers appear on the grid with a Bonus Clover, the Collect Feature is triggered, instantly collecting their values and increasing winnings. Furthermore, Strike Boost Clovers can trigger the Strike Boost Feature, shaking up the reels with random Multipliers, instant Jackpots, or a shower of additional Bonus Clovers. Once the Bonus Game is initiated, Strike Boost Clovers grab even more, accumulating the value of every Strike Clover that appears in the same spin to unlock enormous reward potential.

For an extra dose of excitement, Bonus Clubs can trigger the Clover Stack Feature during the Main Game, flooding the reels with enough special Clubs to instantly power up the Bonus Game. Packed with high-octane mechanics and electrifying surprises, Clover Strike keeps the adrenaline pumping play after play.

Collect Function

The Strike Boost and Strike Clovers, in combination with any Bonus Clover, activate the Collect Feature. The Collect Feature gathers the values of all Bonus Clovers, including the values of Jackpot symbols, and adds them to the current spin's winnings in the Main Game or to the Total Win in the Bonus Game. In the Bonus Game, the Strike Boost Clover collects the values of all Strike Clovers and other Strike Boost Clovers in the same spin in which it appears.

Strike Boost Function

Each time it appears on the reels, the Strike Boost Clover can trigger the Strike Boost Feature, randomly awarding one of the following prizes: a ×2 multiplier,

×3 or ×5 applied to the value of the Clover Strike Boost for that play; a random Jackpot

awarded immediately; or 2, 3 or 5 additional Bonus Clubs with random values added to the reels.

Bonus Game

The Bonus Game is triggered if the Bonus Clovers land on reels 1 and 3, along with the Strike and Strike Boost Clovers on reel 2. Only the Bonus, Strike, and Strike Boost Clovers can land on the reels during the Bonus Game. The Strike and Strike Boost Clovers only appear on reel 2 and remain there while the feature is active. Each Bonus Clover displays a value of ×1, ×2, ×3, ×5, ×7, ×10, or ×15 times the total bet. At the start of the Bonus Game, 3 new spins are awarded. Each new symbol resets the number of new spins to 3. When the new spins are exhausted, the Bonus Game ends, and the values of all Strike and Strike Boost Clovers are added to the Total Win.

Stack of Clubs Function

Any Bonus Clover that lands on the reels during the Main Game can trigger the Clover Stack Feature, which adds Bonus Clovers, Strike or Strike Boost to activate the Bonus Game.

Prize table

The payout information in the Payout Table already displays the exact monetary value based on the player's bet. The maximum payout is limited to 15,000 times the total bet. If the total winnings in a round reach this limit, the round ends and the prize is paid out immediately.

Randomization

The algorithm used for pseudorandom number generation (PRNG) is a deterministic random bit generator (DRBG). The cryptographically secure implementation (CSPRNG) of the OpenSSL library version 1.1.1f (released March 31, 2020) is used. Background loops and periodic replacement are also employed.

OpenSSL comes with a default implementation of the RAND API based on the DRBG model, as described in [reference to DRBG model]. The Open Source Technology Improvement Fund evaluates the OpenSSL library, and its security assessment can be found [here/online]. 

Error Management

If a player attempts to access a game using an invalid session (for example, due to inactivity or a system restart), an error message is displayed in the game. The player can then log back in and resume playing. The game state is always saved so the player can resume playing exactly where they left off.

In the event of an HTTP error, a network timeout error, or a server error, the player will be shown a "technical error" message.

Players have access to the rules of the game at all times.
