On Thin Ice Season 3 Walkthrough Overview

Season 3 is built around three major systems: Light, Darkness, and Authority. Many dialogue choices affect Light or Darkness, while confident decisions and selected premium options can increase Authority. Your accumulated stats influence later scenes, investigations, competition results, and the final direction of the story.

This season is complete and contains ten episodes, beginning with “Reborn” and ending with “Breaking the Ice.” The most important preparation point is Episode 5, where you need either 100 Light or 100 Darkness for a major route. Episode 9 also checks for 85 Authority, so avoid spending every decision on short-term relationship gains.

The On Thin Ice Season 3 walkthrough reference records individual choice effects, premium costs, relationship branches, and episode stat totals. Use this article as a route-planning guide, then consult the linked episode reference when you need the exact wording of a choice.

Light Route

Favor empathy, recovery, negotiation, and constructive responses. This route can support the Episode 5 option to help Ocean and leads toward a calmer future in Episode 10.

Darkness Route

Favor independence, confrontation, risk, and decisive action. This route supports the Episode 5 option to stop Ocean and can lead toward a freer, more unpredictable future.

Balance Route

Mix Light and Darkness choices. Balance becomes especially important in Episode 10, where you can choose between different life directions rather than following one fixed identity.

Route Planning

Choose your preferred moral direction before starting Episode 1. Mixed choices are viable, but tracking both stats makes the Episode 5 requirement easier to miss.

Episode-by-Episode Choice Priorities

The season’s episodes steadily build toward the Ocean confrontation, the Episode 9 competition, and the final relationship scenes. You do not need to select every premium option to finish the story, but diamond choices can protect relationships, unlock CGs, increase Authority, or improve mastery.

1

Episodes 1–2: Establish Your Route

In “Reborn” and “A Clean Slate,” make your first Light, Darkness, and Authority decisions. Episode 1 includes early relationship checks for Leon, Brian, and Liz. Episode 2 expands the relationship routes with Tate, Hodge, and Dominic while adding several Authority opportunities.

2

Episodes 3–4: Build Relationships and Authority

Episodes 3 and 4 introduce more substantial relationship branches, premium scenes, and investigation choices. The Episode 4 option to ask a friend for help can matter later, especially if you want the special single ending involving Ezekiel.

3

Episode 5: Pass the Ocean Check

“The Climax” is the first major checkpoint. Reach 100 Light to offer help to Ocean or 100 Darkness to take the more aggressive intervention. Authority also changes how Ocean treats the protagonist and can influence the tone of the confrontation.

4

Episodes 6–8: Protect Your Preferred Path

Rehabilitation, The Dangerous Truth, and Mexican Standoff contain further romance scenes, timed choices, mastery opportunities, and Authority gains. Episode 8 can provide up to 10 Authority, making it valuable preparation for Episode 9.

5

Episodes 9–10: Resolve the Main Story

Reach at least 85 Authority before Episode 9’s business decision. Your mastery and Authority combination determines competition placement, while Episode 10 resolves the Shadow route, career direction, club shares, and relationship ending.

EpisodeTitleMain priorities
1RebornStart Light or Darkness path, check Leon, Brian, and Liz relationships
2A Clean SlateBuild Authority, mastery, and Tate, Hodge, or Dominic relationships
3Fly in the OintmentAdvance romance routes, manage birthday outcomes, gain Authority
4The Enemy in the ShadowsMake investigation choices and preserve optional friend assistance
5The ClimaxMeet the 100 Light or 100 Darkness requirement
6RehabilitationContinue romance routes and collect substantial Authority gains
7The Dangerous TruthUse correct timed tactics and strengthen selected relationships
8Mexican StandoffMaximize Authority and prepare for the final investigation
9Destiny UnfoldingMeet 85 Authority, resolve the club decision, and place in competition
10Breaking the IceComplete Shadow, career, club, and relationship endings
Timed Choices

Timed choices can award Authority or produce a less favorable result. In Episode 7, choose “Try manipulation” during the infiltration sequence, then choose the confident response in the later timed confrontation.

Stats, Mastery, and Critical Checks

Authority is the most important secondary statistic in Season 3. It affects how characters respond to the protagonist, changes several path scenes, and is checked directly in Episode 9. Premium decisions are not the only way to gain Authority; several free dialogue choices, timed responses, and strategic actions also provide points.

Mastery becomes especially important in Episode 9. The final competition ranking depends on the combination of High or Low Mastery and High or Low Authority. If you want the best available placement, prioritize intensive mastery options when they appear and avoid unnecessary choices that lower Authority.

EpisodeMaximum Light or Darkness opportunitiesMaximum Authority opportunities
1Several Light, Darkness, or mixed gains+4
2Several Light, Darkness, or mixed gains+5
3Several Light, Darkness, or mixed gains+3
4Several Light, Darkness, or mixed gains+5
5Several Light, Darkness, or mixed gains+8
6Several Light, Darkness, or mixed gains+9
7Several Light, Darkness, or mixed gains+3
8Several Light, Darkness, or mixed gains+10
9Several Light, Darkness, or mixed gains+5
10Several Light, Darkness, or mixed gainsNo Authority gain listed

The maximum values vary because some choices award one stat, both stats, or one of two possible stats. Treat the table as a planning reference rather than a requirement to collect every available point.

Authority Focus

Choose confident responses, investigate carefully, and use selected premium actions that explicitly award Authority. Avoid choices marked with an Authority loss.

Mastery Focus

Pick intensive practice options in Episodes 2, 3, 7, and 9 when mastery is your priority. These choices may require diamonds.

Resource Focus

Save diamonds for relationship scenes, Authority gains, mastery options, or finale choices. Wardrobe options generally do not change stats unless the choice states otherwise.

Best Checkpoint Strategy

Before Episode 5, confirm that Light or Darkness is approaching 100. Before Episode 9, confirm that Authority is approaching 85 and that your preferred relationship remains active.

Romance Routes and Ending Preparation

Season 3 supports relationship routes with Hodge, Brian, Liz, Tate, Leon, and Dominic. Relationship scenes usually offer a premium option that significantly improves the relationship and a free option that preserves the route without the same increase. Choosing one character for a major romantic commitment can end or weaken competing relationships.

Episode 10 provides individual ending scenes for each major love interest. These scenes include a look selection, a conversation choice, and a final premium or free decision. The specific ending is determined by your relationship status and the choices made throughout the season.

Love interestImportant Season 3 opportunitiesEpisode 10 ending focus
HodgeRelationship scenes in Episodes 2, 4, and 8Decide whether to continue the relationship and accept a future plan
BrianRelationship scenes in Episodes 1, 3, and 6Continue the relationship through a moving and future-focused ending
LizRelationship scenes in Episodes 1, 3, and 7Resolve personal concerns and choose whether to share the final outing
TateRelationship scenes in Episodes 2, 4, 7, and 8Continue the route through a travel-related closing scene
LeonRelationship checks in Episodes 1, 3, and 9Decide whether to take the next step and join his future
DominicRelationship scenes in Episodes 2, 6, and 7Complete the route through a personal final invitation

To protect a route, select that character’s relationship options consistently and be cautious when the story warns that a decision will end another romantic relationship. Episode 1 contains especially important Leon checks, while Episodes 3, 4, 6, 7, and 8 provide major opportunities for other routes.

Relationship Route Checklist:

  • Choose one primary love interest before making major commitment decisions
  • Select relationship options consistently across Episodes 1 through 9
  • Check whether a premium scene improves the relationship or unlocks a CG
  • Avoid selecting a competing commitment when the route warning appears
  • Confirm the preferred relationship before starting Episode 10
Romance Advice

Free choices can keep a route available, but premium scenes often provide the largest relationship increases. Prioritize the character whose Episode 10 ending you want to see.

Episode 9 and Episode 10 Endings

Episode 9 is the final major setup chapter. At least 85 Authority is needed for the specified business route involving Hodge’s club. The protagonist’s choice about selling Sirius Club also affects Episode 10. If the club is not sold, the relationship between Brian and Dominic determines who becomes its head in Hodge’s absence.

The competition result uses two variables:

MasteryAuthorityCompetition placement
HighHighFirst place
HighLowSecond place
LowHighThird place
LowLowFourth place

Episode 10 then resolves the protagonist’s identity and future. Light, Darkness, and Balance routes produce different Shadow scenes. Light leans toward inner peace, university, and volunteer work. Darkness emphasizes freedom, adrenaline, mixology, travel, and an independent lifestyle. Balance allows a final choice between the Light and Darkness directions.

If you finish fourth in the competition, an additional diamond choice can help determine whether the protagonist continues pair figure skating. Higher placements provide a more direct continuation prompt.

The club decision also has distinct results:

  • Selling Sirius Club in Episode 9 produces a direct sold-shares outcome.
  • Giving up the shares in Episode 10 follows the Light direction.
  • Keeping the shares follows the Darkness direction and can unlock the Business Lady achievement.
  • On the Balance route, you can choose whether to give up or keep the shares.
Finale Preparation

Make a save before Episode 9 if your platform supports it. The Authority check, competition placement, club decision, and relationship ending all influence the final episode’s available scenes.

Q: What is the most important requirement in the On Thin Ice season 3 walkthrough?

The two clearest checks are 100 Light or 100 Darkness for the Episode 5 Ocean route and 85 Authority for the Episode 9 business decision.

Q: Can I complete Season 3 without buying every diamond choice?

Yes. Free choices can preserve story progression and some relationships, but premium choices may improve relationships, award Authority or mastery, unlock CGs, and open additional scenes.

Q: Which choices determine the Episode 9 competition ranking?

The ranking depends on your Mastery and Authority levels: high in both gives first place, while low in both gives fourth place.

Q: Can I change my romance route in Episode 10?

Episode 10 confirms or ends several relationships, but it is safer to build your preferred route consistently from earlier episodes rather than waiting until the finale.
