The Final Puzzle is the closing challenge of The Hunt: Roblox 20, Roblox’s platform-wide 20th anniversary event. It sits under a giant gold trophy in the event hub’s Infinity section, and clearing it is the only way to earn the two rarest items in the entire event: a rainbow-hued Dominus limited to a handful of players, and a matching cape for everyone who reaches the end.
Quick answer: The Final Puzzle opens after you collect all 40 event badges (20 regular, 20 secret). Completing it grants the Amictus Infinitum cape; the Dominus Infinitum went to the first 20 players worldwide who finished on September 26.
What unlocks the Final Puzzle
The standard route to the Final Puzzle runs through the full badge set. You need every badge the event hands out before the trophy will open for you. What follows covers how to unlock the puzzle; the puzzle’s own mechanics are not confirmed and are covered separately once they are.
- 20 regular badges — one from each of the 20 participating games, earned by finishing that game’s event quest.
- 20 secret badges — one hidden quest per game, tracked as Secret Tokens in the hub.
- 40 badges total — once all of them are collected, the Final Puzzle becomes available at the trophy.
The secret badges released in waves rather than all at once, so completion for most players depended on the last batch going live. There are no codes and no Robux shortcut for any of this. Every finale reward is earned through play.
Early access through Secret Challenge leaderboards
The trophy inscription gives the quicker route: finish among the 20 highest-ranked players on a Secret Challenge board in any participating game, and the Final Puzzle becomes available before you meet the full-completion requirement.
Each game’s Secret Challenge board ranks players by their completion time for that game’s secret quest. With 20 games offering 20 places apiece, no more than 400 players can take this shortcut across the event. When a board’s 20 places are filled, that route closes for that game; everyone else must follow the usual 40-badge path.
Secret leaderboards rolled out gradually, with placeholder boards appearing in game hubs before they went live. A board that reads empty is not proof the mechanic is missing from that game.
The finale rewards: Dominus Infinitum and Amictus Infinitum
Reaching the Final Puzzle does not give everyone the same prize. Placement at the finish line decides which of the two items you walk away with.
| Result | Reward |
|---|---|
| First 20 players worldwide to complete the Final Puzzle | Dominus Infinitum |
| Everyone else who completes it (all 40 badges) | Amictus Infinitum cape |
Dominus Infinitum
The grand prize, Dominus Infinitum, goes only to the first 20 people worldwide who beat the finale. This iridescent, glass-textured Dominus hood features glowing pink “X” eye visors and animated sparkle particles. Its catalog entry displays “Ab initio, ad vicesimus”—Latin meaning “from the start up to the twentieth,” a reference to the 20th anniversary. The item is listed as unavailable for sale, so Robux cannot be used to buy it.
Amictus Infinitum
The Amictus Infinitum goes to every other player who finishes the event. This flowing, iridescent rainbow cape has an animated particle effect that keeps emanating from the item. As with the Dominus, the catalog listing says it is unavailable for purchase, leaving full event completion as the only way to earn it.
The Admin Abuse bonus in +1 Speed Keyboard Escape
A separate, scheduled event was offered at a red countdown station in the hub, labeled “Admin Abuse.” Its prompt teleported players into +1 Speed Keyboard Escape, and attending that session before the finale opened granted a small bonus toward the Final Puzzle. The station originally read “Play to unlock the final puzzle early!” before developers changed the wording to a small bonus following community feedback.
The bonus applied to the final battle tied to completing the puzzle. It was a scheduled one-off rather than always-on, so it only helped players who joined during its window, and no repeat session has been indicated.
When the finale opened and how long rewards last
The Hunt: Roblox 20 runs September 17 through 28, 2026. Secret badges arrived on a staggered schedule across the back half of the event, with the finale following the last drop. The Final Puzzle opened on September 26, with leaderboard early-access players getting in ahead of the general unlock.
The Dominus Infinitum went to the first 20 finishers on September 26 and is no longer up for grabs. The Amictus Infinitum remains earnable until the event closes on September 28 at 17:00 UTC. After that window, the cape — and the free UGC rewards from the 20 games — stop being obtainable.
You will know the finale worked when the Amictus Infinitum appears in your avatar inventory. The Dominus Infinitum was granted only to completions that landed within the first 20 worldwide on September 26, so a finish now secures the cape without the Dominus.
