Container Simulator

Running-total luck bars use the Container Calculator's mean, percentile ranges, and comparison labels, calculated over 100,000 repeatable simulations of this session's ordered container openings. Luck calculations run locally across up to eight background workers. Preliminary estimates appear after 5,000 and 20,000 trials, then finish at 100,000. During an opening, previous bars stay visible and are marked as updating; the new comparison starts when the batch finishes. Results stay in your browser unless you choose Share opening. Each trial starts with your session's starting ship collection and zero counters, and repeats collection-subscription choices. Ship luck measures all ships together and each WG ship pool, with individual names listed inside their pool. Other bars measure drops of that exact reward, not total resource units. The Average range selector sets the central interval counted as typical, defaulting to the middle 25%. Results on either boundary count as typical; the arithmetic mean does not change. Nested-opening comparisons use the types and quantities you chose to open, without conditioning parent rolls on earning those containers. Ship pools remain visible even when no ships have dropped. Guarantees, depleted pools, and compensation are included in the comparison; compensation is listed as its actual resource reward.

Every opening is appended to the session container log. Running totals include all batches and container types, and export contains the complete session. The intact container fades away as its reward pops up. Batch rewards then fall aside. Choose up to five highlights or a reward from every container. The manifest updates after each reveal: every-container mode adds that container, and highlights add the represented group. Skipping records the remaining openings immediately.

This is a free fan-made simulation using the same public Wargaming data as the Container Calculator. Nothing is purchased or added to your World of Warships account. Random outcomes are generated in your browser.

Each session starts with your selected ship collection and zero guarantee counters. Connecting WG imports your current Port using the same account service as the Container Calculator. You can edit the starting collection before opening containers. Reset keeps that starting collection and unlocks editing; reloading retrieves the connected Port again. Counters remain separate for each container variant; acquired unique items are shared across your session. Opening another batch continues those counters. Resetting the session or reloading the page clears them.

The simulator uses published reward weights, per-slot and container guarantees, and compensation when all eligible unique items are collected. Exhausted unique groups redistribute their combined chance in proportion to the remaining group weights. WG’s repeatable groups can drop duplicates; crew reroll groups avoid repeats until every commander in their pool is collected, then allow duplicates at the same drop chance. Commander drops do not turn into ships or unique-item compensation when the roster is complete. Container-specific account compensation rules not included in the public data cannot be reproduced.

Eligible daily containers also roll for a random patch (15%), and a collection element (60%) when you select “Subscribed to a collection.” These bonus results are reported by category. Containers received as rewards have an Open button in the totals and log. Open uses one unopened container. Open all uses the remaining balance shown beside it and appends every result to this session. In the container log, Open all applies to that specific drop. Newly received containers remain unopened. Totals retain the full amount received, with the remaining unopened balance shown separately. Ship rewards show the supplied commander level. Clan and account modifiers are not applied.

Ten containers have signature 3D reward reveals with distinct motion, light, particles, and sound. Other containers use the shared reveal. Rewards use WG’s artwork. Animations and opening sounds default to on and can be disabled independently. The playback checkbox takes precedence over your device’s reduced-motion setting. Opening containers does not automatically scroll the page or expand collapsed panels. Sounds are created in your browser and only start after you open a container. Animation choice never changes your rewards.
