• Scatter symbol: the box symbol with jewels (Jewel Box) serves as a bonus symbol and appears only on reels 1, 3, and 5. Three such symbols trigger the bonus game.
• Bonus game: when three box symbols appear, the game 'Choose and Click' is activated, where the player must choose one of three boxes, each containing a unique prize. This can be a cash win or additional bonuses.
• Risk Function (Gamble): after any winning combination, the player can double their win by guessing the card color in the classic game for doubling. This function is available after each win.

The slot features traditional non-paying spins (frispins), which is a feature of this machine. Instead of this, the developer made an accent on the bonus game and risk function.

Expert opinions and recommendations

Jewel Box presents a classic video slot with a proven mechanic and appealing theme. The average volatility makes it suitable for both cautious players and those ready for higher risk bets.

Strategies for maximizing winnings

• Start with minimal bets: use minimal bets (0.01 credits) to study the game mechanics and determine the frequency of bonus symbol drops.
• Activate all lines: for maximum coverage, always play all 15 lines to not miss potential winning combinations.
• Use the autoplay function: the autoplay feature allows you to set a specific number of spins, which is especially useful when waiting for a bonus game.
• Reasonably approach the gamble function: the doubling function can significantly increase wins, but it also carries the risk of total loss. Use it only with small wins.
• Manage bankroll: with average volatility, it is recommended to have a bankroll at least 200-300 times larger than the minimum bet for a comfortable game.

Mathematical model

• Volatility: average — provides balanced gameplay with regular small wins and the possibility of large payouts when activating bonus functions.
• Chances of winning:
  • Average frequency of bonus symbol drops — typically once in 187 spins.
  • The probability of a wild symbol drop with a multiplier — moderate.
  • Chances for maximum win (2500x) — low, but achievable.
