Slot free games feature explained: how the round starts, grows and ends

How scatters set off the round

Most symbols pay only when they sit in the right place: along a payline, or in a run of adjacent reels on a ways game. A scatter ignores all of that. Once the reels stop, the game counts the scatters showing anywhere in the window, and if the count reaches the number in the pay table, the free games begin.

That number is set game by game. Springbok's Shadow Gods preview asks for 3 or more Mask scatters, while the lobby tile for Olympus Thunderhold wants 4 or more Zeus scatters. Some games also limit where a scatter may fall: Springbok's review of Coyote Cash 2 says its scatters must appear on reels 1, 3 and 5.

The trigger is decided in the same instant as the rest of the spin, by the same random draw. It cannot be stored up, and a long wait does not bring it any closer: the chance of the next spin starting the feature is the same after fifty empty spins as it was after a lucky one.

These are examples from the slots in our spec file, not a complete list of the lobby's 244 slots. Notice how much the round size varies: some games state an exact count, some a range, and some only an "up to" ceiling.

What changes once the free games start

A free-games round is seldom the base game replayed at no cost. Designers nearly always change one rule for its duration, because the feature carries a large share of what the game pays back over time. On the slots in our spec file, those changes fall into three families.

None of these extras lifts the return a game was built to pay over the long run. They decide where in a session that return tends to arrive. When a big part of it sits inside the feature, the base game between triggers has to pay less to make room, and that trade-off is much of what the lobby's volatility label sums up (how volatility shapes a session).

Retriggers: how a round extends itself

A retrigger adds games to a round that is already running, usually because the trigger symbols land again during the free games. It is the main reason two rounds of the same feature can end up very different lengths.

The rules differ more than the word suggests. Springbok's Shadow Gods preview adds 6 games each time. Olympus Thunderhold's tile sets a lower bar inside the feature than outside it: 3 or more scatters add 5 games, against 4 or more to start. Springbok's review of Big Cat Links adds 5 games for each further 3 scatters, and its review of Vegas XL says that round can retrigger up to three more times.

Pick-a-mode rounds: Wild Reels or Treasure Spins

Some games ask you to decide before the free games begin. In Shadow Gods (Springbok's press release says it arrives on 14 October 2026; it was not in the lobby when we checked on 9 October 2026), the preview says the Mask scatters lead to a choice between Wild Reels and Treasure Spins, with 6 free games either way. Count Spectacular is an older take on the idea: a Springbok article says the Count landing on reels 1 and 5 offers a choice of 12 free games with triple prizes or 4 re-spins.

In most pick-a-mode games the options trade how often the round pays against how much: one leans on steadier, smaller wins, the other saves its value for fewer, larger ones. Whether Shadow Gods is built that way is not published. Springbok's preview names the two modes and their length, and gives no return figure or hit rate for either, so there is no published basis for calling one the better pick.

Free games in a slot vs free spins from a coupon

The two names get swapped all the time, but they are different things. Free games are part of a slot's design: the reels award them during play, and their wins count the same way as the spin that started the round. Free spins from a promotion are a bonus Springbok gives you, tied to one game and to the bonus rules in its T&Cs.

Springbok's terms set out how those promotional spins are treated, and the rule is stricter than many expect.

Free-spin winnings must be wagered 60x the initial free-spins value in ZAR; at most 5x that value can be withdrawn; free spins are tied to one game Verified, 9 October 2026

A round the slot awards by itself carries only the rules already attached to the money you were playing with. Springbok's monthly free-spins coupon, while one is current, is shown below with its game, wagering and cap.

Free games, your budget and the Buy Feature

With so much of the return packed into the feature, the stretch between triggers often feels lean. Budget as if the round may not come at all.

A few games let you pay to skip the wait. Olympus Thunderhold's lobby tile lists a Buy Feature at 100x the bet, and Bass Baggin' Bounty's tile names a Buy Feature too. Buying turns many small stakes into one large one: at an example stake of R2 a spin, a round priced at 100x costs R200 in a single tap, and the round it buys can return less than that.

If waiting for the feature has become the reason you keep spinning, take a break. Free, confidential help is on 0800 006 008 or WhatsApp 076 675 0710, and the responsible play page explains the limits Springbok lets you set.
