The free spins bonus round in online slots games awards payouts to players without their staking any amount. Obviously this is compensated for by slightly lowering the payouts in the normal rounds. Activating the free spins bonus is a matter of chance. It is natural for players who do not get to play this round even after long stints of wagering to feel aggrieved. The leading online gaming software provider Realtime Gaming (RTG) has removed this heartburn by introducing a feature called Feature Guarantee. Feature Guarantee offers a mechanism that ensures players will get to play the free spins round if they are patient enough.

In the RTG online slot games with Feature Guarantee, the free spins bonus is set to automatically activate after at most 150 spins. The Feature Guarantee counter appears on the top right hand corner of the game screen. The initial setting is 150. After every spin counter decreases by 1 count. After 150 spins, when the counter will reach 0 the free spins bonus round will automatically be activated. Then the counter will reset to 150 and the same process will be followed. It is possible that the player gets the alignment on the reels for activating the free spins before the mandatory 150 spins. In that event the free spins bonus round will be awarded irrespective of the counter reading. After the free spins the counter will be reset to 150. Players should note that if they change the betting parameters then the counter will reset to 150 without awarding free spins.

The conservative players can follow the above procedure. The more aggressive players can utilize the Instant Trigger Chance. This gives the player a chance of activating the free spins bonus without waiting for 150 spins and without getting the required combination of symbols on the reels. However, if the Instant Trigger Chance fails, then the Feature Guarantee counter will reset to 150 without the player having activated the free spins.

The Instant Trigger Chance Counter is below the Feature Guarantee counter. It indicates the probability of success if the trigger is activated at that point. As the Feature Guarantee counter decreases to 0, the Instant Trigger Chance counter increases to 100%. The rate of increase is low at first but goes up later. Next to the Instant Trigger Chance Counter is the Play button. Whenever the player wants to take a chance for instantly activating the free spins bonus he can click the Play button. This activates the Feature Guarantee screen, which displays a circle with red and green bands around the circumference. The proportion of green bands corresponds to the probability of instantly triggering the free spins bonus round. When the player activates the Instant Trigger Chance, the green bands randomly get scattered around the circumference. A tracker rotates around the circumference and comes to a stop. If it stops on a green band the free spins bonus round gets activated. But if it stops on a red band the main game is again activated. In either case the Feature Guarantee counter is reset to 150.

Aztec’s Treasure, It’s A Mystery and Mice Dice are some of the Realtime Gaming online slot games that incorporate the Feature Guarantee. These can be played at online casinos like Win Palace, Manhattan Slots and Slots Jungle.
