Amber Archive

Amber Archive is an optimal merging puzzle in an illustrated amber library. Each volume starts with a collection of weighted bundles. Select two bundles and bind them together. Their weights add, and the new combined weight is also added to your total binding cost. Continue until only one bundle remains. The goal is to finish at the exact minimum cost shown above the desk. Every original bundle must be included. A merge that looks convenient now may create a heavy bundle that becomes expensive to merge again later. Compare small weights and think about how often each part will contribute to the final cost. Each bundle retains a parenthesized description of its contents. Selecting it marks it with a tick; selecting a second bundle prepares the pair for Bind. Hint selects a suitable pair without applying the merge. Undo restores the previous collection and its accumulated cost. The cost readout also tells you when the current branch can no longer achieve the optimum. You can recover with Undo or restart the volume. Fifty different starting collections are included. There is no timer or move-speed requirement. Warm manuscript illustration, an amber owl and brass details frame the archive, while the working bundles remain native text controls. YOUR CHALLENGE COLLECTION All fifty challenges are available from Play. Choose any one, revisit a completed challenge or use Continue to open the last selected entry. Completion marks and settings are saved locally on the device. Continue starts that challenge from its initial arrangement; unfinished attempts are not restored. Restart asks before discarding the current attempt. After a successful challenge, you can advance to the next one or return to the collection.
