Raft Hidden Achievements Guide: All 19 Hidden Achievements and Only Their Unlock Conditions

These three need no specific island and no story progress, only repetition or depth. Break or pick up 100 blocks for the first, die 25 times for the second, and reach 100 meters below the surface for the third. The death counter is the one players most often grind on purpose: guides note that a fresh save can be used for it, so it does not have to cost your main run.

Two rare small islands each carry one hidden achievement, and neither can be aimed at directly. Small islands spawn at random, and guides put the rare islands at roughly 2% of small-island spawns, so these two are a matter of sailing and checking, not of following a route. One is a crashed plane, the other is a shipwreck island known as Captains Island. Discovering the island is the trigger in both cases.

All three Balboa achievements are single interactions, and all three are easy to walk past. Follow the bell sound to a bicycle bell and press it, look behind the toolboard, and interact with the scarecrow on a hill facing the Mama Bear cave. Each trigger is one action; none of them needs a fight or a fetch.

Tangaroa holds four hidden achievements, and each one is a distinct place or object inside the city. Find the secret room behind the boxes in the cargo area, play a note on a piano, activate the Emergency Bridge Launch in the central tower, and go twenty floors down in the central elevator. The piano is bought from a Tangaroa vending machine for 8 tokens, placed on the raft, and played at least once. This guide deliberately does not print the launch code: the code is beyond the condition, and it is found from panels in the city itself.

Two of these are set-completion achievements, and the third is recipe completion. Find and place all developer paintings for Artistic Collection!, collect all four Tiki pieces while metal detecting and place them in the correct order for Former Glory!, and learn all crafting recipes from Decoration Packages for The Renovator!. The honest gap in this section is the painting count: sources conflict on the exact split between dug-up and bought paintings, and the wiki states only the condition, so this guide prints the condition and does not invent a count.

The last four are story milestones, and this guide states each one in the fewest words the condition allows. Find the white board in the radio station, breach the cockpit of Vasagatan, slay the boss at Varuna Point, and finish the game. Nothing more is said about any of them here, because the condition is the whole point of this guide.

Because Steam hides hidden achievement descriptions until the achievement is earned. The names and global percentages in this guide come from the schema pull, and the conditions come from the official wiki and player guides, not from Steam descriptions.

Artistic Collection! at 1.0%, followed by Former Glory! at 1.1%. Both are set-completion achievements, which is why they sit at the bottom.

Only the painting count for Artistic Collection! is unconfirmed. The condition itself, find and place all developer paintings, is verified; the split between dug-up and bought paintings is not, so no count is printed.

Sources and honesty notes: achievement names, hidden flags, and global percentages come from the Steam schema and percentage pull for app 648800 in the file supplied for this column. Hidden achievements carry no description in that file, so conditions were verified against the official Raft wiki achievements page and Steam community 100% and hidden-achievement guides. The launch code for Launch Initiated! is deliberately not printed, and the painting count for Artistic Collection! is deliberately not stated, for the reasons given in the article.
