About Book of Time

Book of Time is a 5×4, 20-payline slot with two main bonus modes. It’s a Classic! is a “book-mechanic” feature where 1–3 symbols are chosen as special; when any land on three or more reels, they expand to cover them and pay anywhere. Landing 3 Books adds +5 spins and +1 special symbol until the bar is full. The Book isn’t wild here. What Time Is It? triggers with three Clock Man scatters for 10 spins. Clocks above reels 2–4 show new times each spin; when a Clock Activator lands, Wild Multiplier Clocks (WILD, 2×–12×) drop down, replacing symbols and stacking multipliers on wins. Max win 10,000×, base RTP 96.13%, FeatureSpins™ RTPs shown, stakes 0.10–100.00, 20 fixed lines.

Classic Book Feature

The Book symbol acts as both Wild and Scatter. In the base game, it substitutes for all paying symbols and can trigger the Classic bonus when 3, 4, or 5 land, awarding 10, 15, or 20 free spins with up to 3 special symbols. During the feature, 3 additional Books retrigger +5 spins and add one extra special symbol. The Book does not appear in the What Time Is It? mode. When appearing as part of a payline, 5 Books award 500× the bet. It cannot be chosen as a special symbol during free spins but remains central to triggering the feature.

Expanding Special Symbols

During the It’s a Classic! feature, any selected special symbol expands to cover full reels when landing on at least three. After expanding, these symbols pay anywhere on the grid, ignoring standard paylines. If multiple special symbols appear, each expands and pays one after another. The Book symbol only triggers the feature and does not participate in special-symbol payouts. Landing 3 Books during the round awards 5 extra spins and adds 1 additional special symbol, up to the maximum limit.

What Time Is It? Bonus

The What Time Is It? feature activates when three Clock Man scatters appear in the base game, granting 10 free spins. Clocks positioned above reels 2, 3, and 4 display a new time with every spin. When a Clock Activator lands on these reels, Wild Multiplier Clocks cascade from the top, replacing all symbols down to the Activator. Each reel’s multiplier value corresponds to the time displayed above it, creating dynamic and unpredictable win potential.

Multiplier Clock

The Multiplier Clock boosts wins when part of a winning line. If multiple Clocks appear together, their multiplier values combine before being applied to the payout. Each Multiplier Clock can display values of WILD, 2×, 3×, 4×, 5×, 6×, 7×, 8×, 9×, 10×, 11×, or 12×, making every connection potentially explosive in value.

How to Play Book of Time

Set your bet within the visible 0.10–100.00 range. Wins pay on 20 fixed lines from left to right; only the highest win per line is paid. Use the spin button to start rounds, or enable Autoplay and set limits in Advanced Autoplay Settings (number of plays, session loss limit, single win limit). Turbo Play can be toggled from the menu where available to speed up rounds. Base game: The Book acts as a wild substitute for all paying symbols. The Clock Man symbol appears only in base and is responsible for triggering the What Time Is It? feature when three land. Line wins are shown during the win presentation; multiple wins in a round are summed into the total win field. It’s a Classic! free spins: Landing 3/4/5 Books awards 10/15/20 free spins and selects 1/2/3 special symbols for the duration. When a special lands on at least three reels, it spreads to cover those reels after normal wins, then pays anywhere (paylines can be non-contiguous). If multiple specials land and spread in the same spin, wins are created one at a time. During this feature the Book is not wild and cannot be part of special-symbol “pay anywhere” wins. Retriggers: 3 Books add +5 spins and +1 extra special symbol; this can occur until the special-symbol bar above the grid is filled. What Time Is It? free spins: Three Clock Man scatters grant 10 spins. Clocks above reels 2–4 show new times each spin. When a Clock Activator lands on reels 2/3/4, Wild Multiplier Clocks descend from the top to the activator, replacing symbols on their path. Each reel involved gains a multiplier shown on its clock (possible values WILD, 2× to 12×). If more than one Multiplier Clock contributes to a winning line, their multiplier values are added together first and then applied to the win. FeatureSpins™ / Bonus Buy: If enabled, the Buy Bonus button provides quick access to modes labeled on-screen, each with its displayed RTP profile. Stake requirements and prices are based on your current bet level. Keybinds visible include toggles for sound/music, bet adjustments (Shift + Arrow Up/Down), fullscreen controls, turbo mode, and shortcuts to Bonus Buy/FeatureSpins™.

Book of Time: clocks, books, and a 10,000×

Grabbed a no-deposit perk (basically free tries) and jumped into Book of Time. First impression—retro paper-patch art with chunky outlines, plus that cheeky clock-face dude. Sounds are clicky and clean; the whole thing feels like a storybook ticking along. Base game teased me with small line hits—A pays up to 15× and those mouse symbols can slap 250× for five, so you always watch the rightmost reel crawl in. Then the Books finally lined up and I hit the Classic bonus—10 spins with one special symbol. When it spread across 3 reels and paid anywhere, my heart popped; it built a tidy ladder fast. Later I triggered What Time Is It? and that’s the spicy one. The Activator dropped, clocks fell from the top, and the multipliers stacked (you can see 2× up to 12×). I had two clocks add together on a line; seeing the total apply after the sum feels great—proper “boom” moment. No 10,000× miracle, but I did snag a near-miss sequence with 75× high symbols and stacked clocks that looked ready to explode. Volatility feels punchy but not cruel—stretches of calm, then bursts of action. I’d play again, especially with bonus spins attached; the two distinct features keep it fresh.
