Astro Pets - Hold & Win

Astro Pets - Hold and Win pairs a space exploration theme with Nucleus Gaming's Hold and Win mechanic, sending cartoon animals into orbit on a 5-payline grid. The bonus phase runs on the studio's familiar respin-and-lock structure, but adds two specialist symbols: the Boost symbol that increases coin values and extends respins during the Hold and Win, and the Astro Bonus symbol that delivers a direct cash award when it lands in the bonus. High volatility and a 31.07% hit frequency describe a game where base play moves at a steady clip but the meaningful wins come from the Hold and Win sessions. Available on desktop and mobile with crypto at Wild.io.

What is Astro Pets - Hold & Win?

Astro Pets - Hold and Win is a video slot from Nucleus Gaming with a 96.18% RTP, high volatility, 5 paylines, and a 31.07% hit frequency. Its standout mechanic is a Hold and Win bonus where the Boost symbol actively increases coin values and extends respins, compounding the total on screen before the round ends.

The combination of high volatility and a 31.07% hit frequency is notable: the game delivers wins on roughly one in three spins, but high volatility signals that those wins vary substantially in size. The Hold and Win is the primary vehicle for larger outcomes, with the Boost symbol providing a ceiling-expanding function that other Nucleus Hold and Win titles do not always include. The Astro Bonus symbol adds a direct prize deposit to the mechanic pool.

How To Play Astro Pets - Hold & Win Slot - Step By Step

Head to Wild.io and create a free account to start playing Astro Pets - Hold & Win.

1. Open Astro Pets - Hold and Win at Wild.io and set your stake across the 5 paylines.
2. In the base game, match animal symbols on the paylines for regular wins. The 31.07% hit frequency means a win every few spins on average.
3. Trigger the Hold and Win feature by landing the required number of bonus coin symbols on the reels in a single spin.
4. During the Hold and Win, each landed coin locks in position and 3 respins begin. Every additional coin that lands resets the counter to 3.
5. Watch for the Boost symbol: when it lands during the Hold and Win, it increases the values of coins already on the board and extends the respin session, compounding the total before the round ends.
6. The Astro Bonus symbol, when it appears in the Hold and Win, awards a direct cash prize added to the accumulating coin total.
7. The round ends when respins run out with no new coins landing. The total of all locked coins converts to a payout.

Astro Pets - Hold & Win Slot Theme & Graphics

Nucleus Gaming puts cartoon animals in space suits on a backdrop of stars, planets, and orbital debris. The aesthetic leans toward the playful end of sci-fi: soft pastel space suits on chunky round characters rather than the hard-edged metallic look of more serious space titles. Each animal has a distinct personality through its suit design and expression, and the background cycles through deep-space panoramas with slow star drift animations.

The Hold and Win phase shifts the visual tone: the background darkens, coin symbols lock with a soft glow, and the Boost symbol fires with an escalating light pulse when it triggers the value increase. Audio separates the two phases clearly, with a gentle orbital hum in the base game and a tighter, higher-energy track during the Hold and Win. The 5-payline structure keeps the screen uncluttered, which suits the character-forward art direction.

Astro Pets - Hold & Win Slot Symbols & Paytables

Astro Pets uses two distinct symbol sets: the standard paying symbols for base game paylines, and the specialized Hold and Win symbols that only function during the bonus phase. The payline symbols are all space-suited animals; the Hold and Win symbols are the game's primary payout drivers.

Low Value Symbols

The low-value paying symbols are the smaller and more common space animals, with lower individual payout multiples. They land frequently enough to support the 31.07% hit frequency during base play, providing the win stream between Hold and Win triggers. Their presence in large numbers on the 5 paylines means the base game rarely goes too long without a small return.

High Value Symbols

The high-value animal symbols are the larger or rarer creatures in the Astro Pets cast, paying larger multiples for three, four, or five matching symbols on a payline. These are the premium symbols that make base game wins meaningful when they land in full-reel combinations. Five of a kind on a single payline across any of the high-value animal symbols constitutes the largest standard pay event outside the Hold and Win bonus.

Special Symbols

The Hold and Win bonus coins lock in place when they land and display a cash value. The Boost symbol is unique to this game within the Nucleus Hold and Win series: it increases the values of all coins currently locked on the grid and extends the respin count, allowing the accumulating total to grow further before the round resolves. The Astro Bonus symbol appears during the Hold and Win and delivers a direct fixed cash award added to the coin total. Wild and scatter symbols handle base game payline substitution and potential bonus triggers respectively.

Astro Pets - Hold & Win Bonus Feature & Special Features

Hold and Win with Boost Symbol

The Hold and Win feature in Astro Pets follows the standard Nucleus framework: bonus coins land, lock, and 3 respins run with the counter resetting on each new coin. The differentiating mechanic is the Boost symbol. When Boost lands during the active Hold and Win phase, it applies an upward adjustment to the values of all coins already locked on the grid, effectively increasing the accumulated total mid-session. It also extends the respin count, giving more opportunities for additional coins to land and push the total further. This compounding function makes a Boost-heavy Hold and Win session produce substantially more than a similarly coin-populated session without Boost.

Astro Bonus Symbol

The Astro Bonus symbol operates exclusively within the Hold and Win phase. When it lands on the grid during the respin sequence, it deposits a fixed cash prize directly into the running total, separate from the coin values already accumulated. It does not lock like a Bonus coin but its award is immediate and added to the total payout pool. In sessions where the Boost has already inflated coin values, an Astro Bonus landing on top adds a clean fixed amount to an already escalating sum, making the two symbols particularly high-value when they both appear in the same Hold and Win session.
